Ping-post is how most internet leads are actually sold: the second a consumer hits submit, a stripped-down summary of that lead is pinged out to many buyers at once, each buyer’s system decides whether it fits and what it is worth, and only the winning bidder is posted the full record with the person’s name and phone number. The losers never see the personal data. The entire auction runs in the seconds after the click. It is a genuinely good design, and if you buy leads at any volume you are already living inside it whether or not anyone explained it to you.
Here is the part the software vendors do not put on the pricing page. That ping carries fit data. It does not carry authenticity data. It tells you a lead claims to be a homeowner in a particular ZIP code who wants a quote. It tells you nothing about whether a real person is behind it. So the auction asks you to name a price for something you have not yet established is real, and it asks you to do it in under a second. This guide teaches the mechanics properly, and then makes the argument that follows from them: lead verification belongs inside the bid decision, not bolted on after the post.
- Ping-post is a two-phase auction. A partial, non-identifying ping fans out to many buyers, they bid, and the full lead is posted to the winner only.
- A ping tree asks many buyers at once and takes the best answer. A waterfall asks price tiers in sequence and stops at the first yes. Production systems blend both.
- Ping-post beats direct post for buyers because you get per-lead control over what you accept and what you pay. That is real, and it is worth having.
- The catch is structural: the ping shows fit, never authenticity. Bots, incentivized and co-registration traffic, aged records, and multi-sold data all ride the same rails in an identical-looking packet.
- Exclusivity is a pricing term, not a quality term. Paying an exclusive price for an unverified lead buys sole ownership of an unknown.
- The fix is placement. Verification that runs before the bid changes your decision. Detection that runs after the post only gives you a dispute.

A word on sourcing before we start, because this topic is almost entirely documented by companies selling into it. Where a mechanic is described the same way by Boberdoo, ActiveProspect, ClickPoint, Phonexa, and Anura independently, we state it plainly. Where a number comes from one vendor describing its own system, we name that vendor and leave the number attributed rather than promoting it to a fact. And we state no lead-fraud percentages at all. There are several in circulation, they disagree with each other, they trace back to companies that sell fraud detection, and the argument here does not need them. We write this as an operator: Elevarus buys media and runs verified-lead funnels, so we sit on both sides of this auction and the only question that matters to us is whether the unit changing hands is real.

What ping-post actually is
The thirty-second version: a lead is offered for sale twice. First as a summary, then as the real thing.
A consumer fills out a form. The seller does not immediately hand that lead to anyone. Instead it takes a partial, non-identifying slice of the submission, the state or ZIP, the coverage or loan type, a handful of qualifying attributes, and transmits that slice to a list of potential buyers simultaneously. That transmission is the ping. Each buyer’s system reads it, checks it against its own filters, and either returns a price or declines. Once the seller has the bids, it awards the lead and delivers the complete record, personal information included, to that one winner. That delivery is the post. ActiveProspect’s own glossary defines ping-post as “method of selling leads based on providing (or ‘pinging’) partial lead information and allowing buyers to bid on the partial lead,” where “the winner is then given (or ‘posted’) the rest of the complete lead data.”
To understand why anyone built this, you have to know what it replaced. ClickPoint describes the old world directly: lead sellers “would sell their internet leads to multiple buyers and then could not control them; the buyers could then potentially sell the lead to other buyers.” You bought a record, you had no idea who else had it, and you had no way to say no to an individual lead before it landed in your CRM. Ping-post fixed a real problem. In ClickPoint’s words it “aligns the needs of buyers and sellers by connecting only the leads that meet a buyer’s profile,” and it does that per lead rather than per contract.
That is worth saying clearly, because the rest of this guide is going to be critical of what the model leaves out, and the criticism is not that ping-post is bad. Ping-post is the best distribution mechanism available to a lead buyer. It gives you granular control that direct post cannot. The problem is that the industry has spent twenty years perfecting the control layer and almost no time on the layer underneath it.
The two-phase flow: what the ping carries, and what it hides
Everything downstream depends on one detail, so it is worth being precise about it: what is actually inside a ping.
A ping is deliberately thin. It contains the attributes a buyer needs in order to price the lead and nothing more. Geography. Product or coverage type. A few qualifying fields specific to the vertical, such as a loan amount, a credit band, or a roof type. What it deliberately does not contain is the consumer’s name, phone number, or email address. That omission is the design working as intended. If every buyer in the tree received full personal data on every ping, the seller would be giving away its inventory to twelve companies in order to sell it to one, and the model would collapse immediately. So the ping is stripped, buyers bid blind on the identity, and only the winner is trusted with the record.
The Two-Phase Flow: Ping, Then Post
One consumer form submission becomes many outbound pings, then exactly one full lead delivery.
Phase 1 – The ping
Partial, non-PII data fans out
The seller strips the submission down to metadata a buyer needs in order to price it: state or ZIP, coverage or loan type, a few qualifying attributes. That stripped record goes to many buyers at once. No name, no phone, no email.
Many buyers see this
Phase 2 – The bid
Buyers filter, then price
Each buyer’s system tests the ping against its own filters for fit, geography, and current capacity, then returns a bid price if and only if it wants the lead. Otherwise it declines and drops out of this auction.
Fit first, price second
Phase 3 – The post
The full lead goes to the winner only
The complete record, personal information included, is delivered to the winning buyer’s endpoint. Buyers who lost the auction never receive the consumer’s personal data. That containment is the design’s whole point.
One buyer sees this
Phase 4 – The fallback
A failed post rolls downhill
If the post to the winner fails on a timeout, an HTTP error, or a rejection, the system re-posts to the second highest bidder, then the third, until someone accepts. The lead rarely dies just because the winner’s endpoint did.
Second bidder, then third
Now look at that list of ping contents again and notice what category of information is missing. Not just PII. Every ping field describes what the lead claims to be. None of them describe whether the claim came from a person. ZIP code is self-reported. Coverage type is self-reported. Loan amount is self-reported. A script filling that form out ten thousand times produces pings that are indistinguishable from a real consumer’s, because the fields a ping carries are exactly the fields a script can populate perfectly.
This is the spine of the whole guide, so here it is in one line. The ping tells you whether a lead fits. It never tells you whether a lead is real. Every mechanic in the rest of this piece, the tree, the waterfall, the bid logic, exclusivity, the fallback re-post, is a sophisticated way of pricing something whose authenticity nobody in the transaction has established.
Ping trees, waterfalls, and the real-time auction
One lead becomes many bids, and there are two shapes for how that happens.
A ping tree is the seller’s ranked list of buyers plus the logic that decides who gets asked and in what order. It is called a tree because one lead branches into many outbound pings at once. Every interested buyer answers at the same time and the lead is awarded to the best answer. A waterfall works the other way, sequentially. Boberdoo describes it as “a specialized option used primarily in the Payday Loan vertical,” in which the system “attempts to sell each lead at the highest price using pricing tiers agreed to by your buyers.” The lead is posted to the highest-priced matching filter set first, and if rejected “it moves to the next highest tier, and so on until a buyer accepts.” In practice the labels describe two ends of a spectrum rather than two separate products, and most real systems blend them, running a parallel tree inside each sequential tier.
Ping Tree Versus Waterfall: Two Ways to Route One Lead
A ping tree asks everyone at once and takes the best answer. A waterfall asks in price order and stops at the first yes.
Ping tree (parallel fan-out)
- The seller keeps a ranked list of buyers, and the ping goes to many of them at the same time.
- Every interested buyer returns a bid simultaneously.
- The lead is awarded on best bid, weighing price and priority together.
- Optimizes for the true market price of that specific lead.
- Called a tree because one lead branches into many outbound pings.
Ask everyone at once
Waterfall (sequential price tiers)
- Buyers are stacked in tiers, highest price at the top.
- The lead is offered to the top tier first, alone.
- If that tier declines, the offer falls to the next tier down.
- Continues tier by tier until a buyer accepts.
- Boberdoo notes this is used primarily in the payday loan vertical.
Ask in price order
What production systems run
- Real platforms blend the two rather than picking one.
- A common shape: a parallel ping tree inside each price tier.
- Sequential fallback between tiers, parallel bidding within them.
- Treat the labels as ends of a spectrum, not two separate products.
- Either way, you are pricing a lead from fit data alone.
The labels are a spectrum
Two mechanics inside the auction surprise people who are new to buying this way.
The first is that the highest bid does not always win. Sellers weight priority alongside price, so a preferred buyer with a slightly lower bid can beat a larger bid from someone further down the tree. If you are buying, this means your relationship and your acceptance behaviour are inputs to whether you win, not just your number. Consistently accepting and paying for what you bid on is worth real money, because it moves you up the tree.
The second is the fallback re-post. If the post to the winning buyer fails, whether from a timeout, an HTTP error, or an outright rejection at the endpoint, the system does not throw the lead away. It re-posts to the second highest bidder, then the third, until someone accepts. This is a sensible piece of engineering and it has a consequence buyers rarely think through: a lead you rejected on a technicality does not vanish, and a lead you won because two buyers ahead of you had a bad endpoint may not be the lead your bid implied.
On speed, be careful about any specific number you are quoted. No independent benchmark for auction latency exists, and every published figure comes from a vendor describing its own architecture. Astoria writes that “this entire auction happens in under 300 milliseconds.” Lead Distro AI publishes a much more granular breakdown of its own seven-layer system, allotting 1,500 to 4,000 milliseconds to the auction step alone, which it says dominates “because it waits for the slowest eligible buyer to respond,” and totalling 1.8 to 2.5 seconds end to end within what it calls a typical three-second auction window. Those two vendor accounts differ by an order of magnitude, which is a fair picture of the state of the evidence rather than a fact you should plan against. The operational point does not depend on resolving them. Your bidding logic has a very short window in which to decide, so any signal you want to use has to be attached to the ping already. You cannot go and look something up mid-auction.
Direct post, ping-post, and the aggregator in between
Three models, and the honest way to compare them is to ask the same three questions of each: how does it distribute, how much control do I get, and where does my quality risk sit.
Direct Post Versus Ping-Post Versus Aggregator
The same three questions asked of each model: how it distributes, how much control you get, and where your quality risk sits.
Model 1
Direct post
The full lead, personal information included, is pushed straight to a buyer, often to several at once. Control is low: you cannot pre-screen before you receive it, and the seller may resell the same record. You find out what you bought after you already have it.
High multi-sold risk
Model 2
Ping-post
A partial ping goes out, buyers bid, the full lead posts to the winner only. Control is high: you filter and price per lead, per attribute, and you can decline any single lead. You can reject at the ping, but only if you hold a quality signal at ping time.
Control, if you have a signal
Model 3
Aggregator or marketplace
Ping-post consolidated behind one integration, with a network of pre-vetted buyers bidding. Control is medium to high, but you are trusting someone else’s vetting. Your exposure equals the quality of a fraud layer you usually cannot inspect.
You inherit their standard
Direct post is the simplest and the least protective. The full lead is pushed straight to your endpoint, frequently to several buyers at once, and you learn what you bought after you already have it. You cannot decline an individual record on its merits, and the seller may resell it. Ping-post inverts that: you see a summary first, you decide per lead, and you pay only for what you accepted. The aggregator or marketplace model is ping-post consolidated behind a single integration, where a network of pre-vetted buyers bids into one pipe. It is operationally much easier, and the trade is that you are trusting somebody else’s vetting standard instead of applying your own. Your exposure becomes the quality of a fraud layer you usually cannot inspect and did not design.
Ranked purely on buyer control, ping-post wins and it is not close. But control over pricing is not the same thing as knowledge of quality, and the model only converts control into protection if there is a real quality signal present at the moment you bid. Without one, all that granular control amounts to a very precise way of paying market rate for an unknown.
Sold once or sold many: what exclusivity actually buys
Exclusive and shared are the two ways the same lead can leave the same auction, and the difference is a business rule the seller configures, not a limit of the technology.
In an exclusive configuration, only the single highest bidder receives the lead. Astoria puts the consequence plainly: “the loser of the auction never sees the consumer’s personal data, protecting privacy and reducing spam.” In a shared or multi-sold configuration, the top two or three bidders each receive the same record at their respective bid prices. The seller’s trade is arithmetic rather than mysterious: several buyers paying a lower price each can total more than one buyer paying a premium, so a seller choosing shared over exclusive is usually choosing gross revenue per lead over price per sale.
For a buyer the calculus runs the other way. Exclusive costs more per lead, and you are not racing another buyer who was sold the same record. It does not mean the consumer has spoken to nobody else. Shared is cheaper per lead, but your conversion rate is split across the buyers who share it and the consumer arrives fatigued. Which one wins on cost per acquired customer rather than cost per lead is genuinely vertical-dependent and worth measuring rather than assuming. We work through that math in one vertical in our guide on exclusive versus shared leads and cost per customer.
But there is a prior question that most exclusivity conversations skip, and it is the hinge of this entire guide.
Exclusivity is a pricing term. It is not a quality term. What an exclusive price buys you is the guarantee that nobody else received this record. It buys you sole ownership. It says nothing whatsoever about whether the record describes a real person who wanted what you sell. If the lead was submitted by a script, exclusivity means you are the only company that paid a premium for it, which is a worse outcome than sharing it. The premium you pay for exclusivity is only rational on a lead whose realness you have already established. On an unverified lead, exclusivity is a surcharge for being alone with a stranger.
The buyer’s playbook: filters, bids, and closing the loop
If you are buying into a tree, three controls decide your results, and most buyers only use two of them well.
Filters decide eligibility. These are the hard gates: geography, product type, the qualifying attributes your sales process actually requires. A filter is binary and it should be genuinely binary, because the fastest way to poison your own numbers is to accept marginal leads on the theory that volume will sort it out. If you cannot service a state, filter the state, do not just bid low on it.
Bids decide price. ActiveProspect describes its LeadConduit flow simply: the “buyer configures bidding logic based on any and all pieces of data submitted with a lead,” and the “buyer returns a bid price if (and only if) they’re interested in purchasing the lead.” Astoria adds what goes into that logic, calling for factors “like current capacity, geographic saturation, historical conversion rates for that lead type, and maximum allowable CPA.” The useful mental model is that your filter says yes or no and your bid says how much, and those are different decisions that deserve different logic. A lead can be eligible and still not be worth much.
Feedback decides whether either of the first two improves. This is the control most buyers never wire up, and it is the one that compounds. Your CRM knows which leads became appointments and which became revenue. Your bidding logic does not, unless you send it back. Without that loop, you are pricing leads on attributes you guessed mattered, and you will keep bidding confidently on sources that ping beautifully and never close. With it, your bid model learns which sources and which attributes actually convert, and it starts pricing them correctly on its own.
That same feedback is what makes paid media work upstream of the auction, which is why it is worth wiring once and using twice. We cover the mechanics of pushing real outcomes back into an ad platform in our guides to Google Ads bid strategies for lead generation and offline conversion tracking. The principle is identical in both places: an algorithm optimizes toward whatever outcome you actually report to it, so if you report form fills, you will get form fills, including the fake ones.
Why ping-post is also a fraud surface
Everything described so far is a distribution system working correctly. Now consider what else it distributes.
The rails that let a good lead find its best price in under a second let a worthless one do exactly the same thing, at exactly the same speed, wearing exactly the same ping packet. This is not a framing invented for this article. Anura, a fraud-detection firm, publishes its explanation of ping-post on its lead-generation fraud page, which is itself the tell: the mechanism and the fraud problem are documented together because they are the same story. Anura defines ping-post as “a lead distribution technology that allows lead sellers to send a partial lead (usually non-sensitive information) to multiple lead buyers in real-time,” and the capability it sells against that backdrop is timing-based, promising that you can “know if the lead is fraudulent before the visitor even finishes filling the form out.”
Hold on to that last phrase, because it is the argument of this guide stated by somebody else. The useful moment is before the form is even complete, which is upstream of the ping, which is upstream of the bid. A company that sells detection is naturally going to say detection is needed, and that is worth noting when you read it. But the structural observation underneath it does not depend on trusting the vendor, because it follows from what we established earlier: the ping shows fit, not authenticity, so the auction has no native way to tell the two apart.
Here is what rides those rails looking clean. Bot-generated form fills, which populate every ping field perfectly because populating fields is all they do. Human click-farm submissions, which are real people entering real-looking data with no intent behind it. Stolen, scraped, or randomized contact data. Duplicate submissions of the same person across multiple sources. Incentivized and co-registration leads, where someone ticked a box for a solar quote on the way to a gift card and their contact details are completely genuine while their interest is zero. Aged and recycled records, a real person with a real need that expired months ago, resold to farm repeated payouts. And multi-sold leads, where the exclusivity you thought you bought was never enforced.
Not one of those is distinguishable from a good lead at ping time, because at ping time you are looking at a ZIP code and a product type.
We map this landscape in full in our pillar on ad fraud in lead generation and OTP verification, and it is worth reading alongside this one, because the two halves fit together: that guide covers who is behind fake leads and how the fraud economy works, while this one covers the machinery that moves them. The vertical and channel detail lives in the spokes. Co-registration leads explains why a genuinely real contact can carry zero intent. Performance Max spam leads covers what happens when an ad platform optimizes toward fake conversions you reported to it. And the vertical pieces on fake HVAC leads and solar lead fraud show how the same junk changes shape depending on what is being sold.
One thing you will not find here is a percentage. There are several widely quoted figures for how much of the lead supply is fraudulent, and we are not going to repeat any of them. They disagree with each other by wide margins, their methodologies are not published in a way anyone can check, and every one of them originates with a company that sells the cure. Estimates vary enormously and the vendors publishing them have an obvious incentive to inflate. The argument does not need a number. It rests on a mechanism, and the mechanism is not in dispute: a ping cannot carry a fact nobody collected.
The fix: verification belongs inside the bid
If the problem is that the auction cannot see authenticity, there are only two places to put a check, and the difference between them is the whole thesis.
Where Verification Sits Changes What It Is Worth
The same check, run at two different moments in the same auction, does two completely different jobs. Illustrative ordering, not a timing benchmark.
Placement A – The default
Detection bolted on after the post
Ping goes out, buyers bid on fit alone, the winner pays and receives the lead. Only then does a scrubbing or detection tool look at it. That yields a report, a dispute, or a credit request. It cannot prevent the purchase, because the purchase already happened.
Recourse is commercial
Placement B – The argument
Verification inside the ping and the bid
Verification runs at capture and its result rides along with the ping, so bidding logic can see whether a real person controlled that phone before it commits a price. That yields a decision: bid, bid lower, or do not bid. The purchase is prevented, not disputed.
Recourse is technical
Why the order matters
Exclusivity is a price term, not a quality term
Paying an exclusive price for an unverified lead buys sole ownership of an unknown. Verification before the bid is what makes an exclusive price rational, because it is the only arrangement where you know what you are bidding on at the moment you bid.
The whole thesis
The industry default is to put it after the post. You bid on fit, you win, you pay, you receive the record, and then a scrubbing or detection tool examines what you already bought. That produces a report, a dispute, and a credit request. What it cannot produce is a decision, because the decision was made a second and a half ago. Your recourse is commercial rather than technical, which means arguing with your source about a return credit and hoping the relationship survives it. Anyone who has run that process at volume knows how much of your team’s week it eats and how rarely you recover the full amount.
The alternative is to put the check before the bid. Verification runs at the moment of capture, and its result travels with the ping, so your bidding logic can see it while it is still deciding. Concretely that means a one-time passcode step confirming that a real person had live access to the phone number they entered, bot and spam detection flagging automated submissions, and real-time validation checking that the contact data is genuinely reachable rather than merely well formatted. To be exact about the terminology, because it gets muddled constantly: a one-time passcode used this way is lead verification, proving a real person is behind a submission. It is not call tracking, which is a different tool that measures what happens to a phone call after it is placed. Different job, different moment, different data.
Placed there, the same check produces something categorically different. Not a report, a decision: bid, bid lower, or do not bid at all. You prevent the purchase instead of disputing it. And the economics change with it, because now the premium you pay for exclusivity is attached to a lead you know is real, which is the only circumstance in which paying that premium was ever the rational move.
This is the gap in the market, and it is a gap of scope rather than competence. The distribution platforms are good at what they build. Boberdoo, ClickPoint, and Phonexa sell auction plumbing and they sell it well. The tree, the bid logic, the routing, the failover, the reporting, all solid. But the plumbing is agnostic about what flows through it, and no amount of routing sophistication tells you whether the unit being routed is a person. Detection vendors like Anura sell the missing signal, and that is a real and useful product, but it arrives as a bolt-on to somebody else’s auction, integrated by whoever remembers to integrate it. Everyone in the chain is optimizing distribution. Almost nobody owns the unit being distributed.
That is the position Elevarus works from. We are an operator, not a software company, and we do not sell you a platform to install. We buy media and run verified-lead funnels, which means verification is not a feature we bolted onto a product; it is a condition of the lead existing in our funnel at all. The check happens at capture, before anything is offered to anybody, because that is the only point at which it can change what gets sold rather than what gets disputed.
We should be straight about the limits of that, because a guide that oversells verification is doing the same thing as the vendors quoting fraud percentages. Verifying a lead proves the phone number is real and in service, that the person submitting had live access to it, and that they were engaged enough to complete an extra step. It removes the cheap, high-volume layer of junk. It does not prove the person needs what you sell, that their timing is right, or that they will answer when you call. A genuinely real, genuinely verified person can still be a soft lead who was mildly curious on a Tuesday. Verification raises the floor so that your qualification work runs on real people. It does not do your qualification work.
How to buy leads without buying fraud
An operator’s checklist. Ask these before you sign, not after the first bad batch.
Ask where in the flow the quality check runs. This is the single most diagnostic question in this guide, and the answer is almost always volunteered vaguely. You want to hear that verification happens at capture and that its result is available at ping time. If what you hear instead is a description of scrubbing, filtering, or a returns process, the check runs after the sale and you are buying dispute rights, not clean leads.
Ask what the ping actually contains. If you are bidding, you should know precisely which fields you are pricing against, and you should be able to name at least one of them that speaks to authenticity rather than fit. If every field is self-reported, your bid is a guess dressed up as logic.
Get exclusivity in writing, with a lookback window. Exclusive is a configuration, not a property of the model, and the word alone means nothing. Ask how it is enforced, for how long, and what happens if the same record surfaces from another source. Then treat the answer as a quality claim you will verify rather than a promise you will trust.
Ask about the fallback re-post. If the winner’s endpoint fails, where does your lead come from and where does it go. Understanding your own position in the tree tells you a lot about what you are actually being offered at the price you are paying.
Rule out incentivized and co-registration traffic explicitly. Get it in writing that leads are not sourced from survey routers, sweepstakes, or reward flows. These records pass every technical check because the contact data is real. Intent is what is missing, and no format validation will ever find that.
Demand source transparency. The actual domains and creatives the traffic came from, not a category label. A source that will not tell you where its leads originate is asking you to accept its quality standard sight unseen.
Wire the feedback loop before you scale spend, not after. Send real outcomes back from your CRM into your bidding logic. Until you do, every optimization you make is based on which leads pinged well, and leads that ping well are precisely the thing fraud is good at manufacturing.
Insist on a replacement policy for unreachable leads. A source that stands behind reachability is a source that measured it. One that will not is telling you something useful.
If you want the vertical-specific version of this, our lead generation hub breaks the same discipline down by market, including under-65 private health, HVAC, and solar, where the qualifying gates and the junk signatures differ enough to matter.
The one sentence to take away
Ping-post solved distribution. It did not solve the unit being distributed, and it was never designed to.
That is not a flaw in the auction. It is a boundary, and knowing where the boundary sits is what separates buyers who compound from buyers who churn through sources every quarter looking for the honest one. The tree will find the market price of whatever you feed it, instantly and precisely. Whether the thing being priced is a person is a question you have to answer somewhere else, and the only placement that changes your outcome instead of your paperwork is before the bid.

Frequently Asked Questions
What are ping-post leads?
Ping-post leads are leads sold through a two-step, real-time auction rather than handed straight to a buyer. When a consumer submits a form, the seller first sends a ping, a stripped-down and non-identifying summary of that lead, such as the state or ZIP code, the product or coverage type, and a few qualifying attributes, out to many potential buyers at once. Each buyer’s system decides whether the lead fits and what it is worth, and returns a bid or declines. The winner is then posted the complete record, including the consumer’s name, phone, and email. Buyers who lost never receive the personal data. ActiveProspect’s own definition describes it as selling leads by pinging partial lead information, letting buyers bid on that partial lead, and then posting the rest of the complete lead data to the winner. The whole cycle runs automatically in the seconds after somebody clicks submit.
What is a ping tree?
A ping tree is the seller’s ranked list of buyers who receive a ping on each lead, and the routing logic that decides who gets asked in what order. It is called a tree because a single lead branches out into many simultaneous outbound pings, one per buyer on the list. Each member of the tree can return a bid, and the lead is awarded on a combination of price and priority rather than price alone, which is why the highest bidder does not automatically win. A high-priority buyer with a slightly lower bid can beat a bigger bid from a lower-priority buyer, depending on how the seller configured the tree. Ping trees are usually contrasted with waterfalls, which offer a lead to price tiers one at a time in sequence instead of asking everybody at once. In practice most production systems blend the two, running a parallel tree inside each sequential price tier.
What is the difference between ping-post and direct post?
The difference is whether you get to look before you buy. In a direct post, the full lead, personal information included, is pushed straight to your endpoint, and often to several buyers at the same time. You cannot pre-screen it, you learn what you bought only after you have it, and nothing structurally stops the seller from selling that same record again. In ping-post, you first receive only a partial, non-identifying ping, your system decides on fit and returns a bid or a decline, and the full record is posted only if you win. ClickPoint describes the problem ping-post was built to solve: before it existed, sellers would send internet leads to multiple buyers and then could not control them, and those buyers could potentially resell the lead onward. Ping-post gives you per-lead control over what you accept and what you pay, which direct post does not.
Are ping-post leads exclusive or shared?
They can be either, and that is a business rule the seller sets, not a technical limit of the system. The same plumbing sells a lead once or several times. In an exclusive configuration only the single highest bidder receives the lead, and Astoria describes the consequence plainly, writing that the loser of the auction never sees the consumer’s personal data. In a shared or multi-sold configuration, the top two or three bidders each receive the same lead at their respective bid prices. The seller’s trade is simple arithmetic: several buyers at a lower price each can out-earn one buyer paying a premium. As a buyer, exclusive costs more per lead and means no other buyer received that record, while shared is cheaper per lead but splits the conversion and fatigues the consumer. Exclusive is a promise about the seller, not about the shopper. It does not mean the consumer has spoken only to you. Always ask which one you are actually buying, and get it in writing, because exclusivity is a configuration rather than a property of the model.
Is it safe to buy ping-post leads?
The model itself is neutral. It is a distribution and pricing mechanism, and it is genuinely better for buyers than direct post because it gives you per-lead control. The risk is not that ping-post is dishonest, it is that the ping carries fit data and not authenticity data. A ping tells you a lead claims to be in a given ZIP code and interested in a given product. It does not tell you whether a real person is behind it. That means the same rails that distribute good leads efficiently also distribute bot-filled forms, incentivized and co-registration traffic, aged and recycled records, and multi-sold data at machine speed, all wearing an identical ping packet. It is telling that Anura, a fraud-detection firm, publishes its explanation of ping-post on the same page as its lead-generation fraud detection. Buying safely means adding a quality signal before you bid rather than avoiding the model.
Can you verify a lead before you bid on it?
Yes, and this is the part of the market that most distribution software leaves to somebody else. Verification can run at the moment of capture, before the ping ever goes out, so that its result travels with the ping and your bidding logic can see it. A one-time passcode step proves a real person had live access to the phone number they entered. Bot and spam detection flags automated or non-human submissions. Real-time validation checks that the contact data is genuine and reachable rather than merely well formatted. Detection vendors describe the same timing: Anura, for instance, says you can know whether a lead is fraudulent before the visitor even finishes filling the form out, which is upstream of the ping and therefore upstream of the bid. The distinction that matters is placement: a check that runs before the bid changes your decision, while a check that runs after the post only gives you a dispute. To be precise on terminology, a one-time passcode used this way is lead verification, proving a real person is behind a submission. It is not call tracking, which measures what happens to a phone call after it is placed.
How fast is a ping-post auction?
Fast enough that it finishes before the consumer has left the thank-you page, but be skeptical of any specific number you are quoted, because no independent benchmark exists and every published figure comes from a vendor describing its own system. As examples rather than standards: Astoria writes that the entire auction happens in under 300 milliseconds. Lead Distro AI publishes a much fuller breakdown of its own seven-layer architecture, allotting 1,500 to 4,000 milliseconds to the auction step alone, which it says dominates because it waits for the slowest eligible buyer to respond, and totalling 1.8 to 2.5 seconds end to end within a typical 3-second auction window. Those two accounts differ by an order of magnitude, which is the honest state of the evidence. The practical takeaway for a buyer is not a target latency. It is that your bidding logic has a very short window in which to decide, so whatever quality signal you want to use has to already be attached to the ping.
Do I need ping-post software to buy leads?
Not necessarily, and this is worth separating from the question of whether you need the model. If you are buying from one or two sources at modest volume, you can often integrate directly with their post endpoint and skip the platform entirely. Distribution software earns its cost when you are managing many sources, many buyers, or both, and you need filtering, deduplication, bid logic, and routing to run without a person in the loop. If you are a seller, the calculation is different, because the tree is how you find the best price for each lead. The more useful question than build-versus-buy is what the platform actually covers. Distribution software sells you the auction plumbing, and it is generally good at that. It does not usually sell you the lead-quality layer, and that gap is yours to close whichever way you buy.
