Quick answers:
- Can I run ads inside Google Discover?
- Does the update change my Demand Gen targeting?
- Is Google Discover available for health insurance ads?
- How do I measure leads from Google Discover?
Two Google changes landed on August 20, and the coverage split them into two different stories. The SEO blogs wrote about publishers and citations. The ads blogs wrote about Demand Gen. If you buy and earn leads across verticals, it is one story, and the two halves point the same direction.
We run both sides of this for a living: paid media and affiliate management, in regulated verticals and unregulated ones. That is the seat this is written from. A news recap tells you what happened. This tells you what to do with it.
What changed on August 20
Discover now takes instructions. In the Discover tab you can tell Google, in plain language through a chat interface, what you want more or less of, and the feed adjusts (Mediapost). The feed used to infer your interests from behavior. Now the user can state them outright.
The second change is Preferred Sources. Google gave publishers an embeddable button that adds their site to a reader’s preferred sources in one click, and that preference now carries into Google’s AI experiences, not just Top Stories (TechCrunch). Google frames it as letting people choose the sources they trust across Search, Discover, and News (Google).
Put the two together and Discover is now an interest graph built on stated intent, with a visible lane for the sources a reader has chosen to trust. That is a better place to be seen. The question is whether you get there by earning it or by buying it.
Why Discover is now more valuable to earn
A feed steered by explicit intent is a higher-intent audience than one steered by guesswork. When a reader tells Google they want more coverage of a topic, the people reading that topic are closer to a decision. For content that answers a real buying question, that is exactly the reader you want in front of.
Preferred Sources is the earned lever. If a reader marks you as a source, your links get a standing chance to show inside the AI answers Google is now putting in front of everyone. That is the same fight we already track on the organic side, where the win is getting cited in the answer, not just ranked under it. Our social search playbook walks through how we measure that lane. The Preferred Sources button is a new, direct way to nudge it.
None of this needs an ad account. It needs content good enough that a reader chooses you on purpose.
Why it is no more useful to buy for lead capture
Here is the part the ads coverage skips. Discover’s only paid channel is Demand Gen, and Demand Gen was built to sell reach, not to capture a lead. Sitelinks are the heaviest asset it takes (Google Ads Help). It has no lead form asset and no call asset: bring either over from an older campaign and the migration refuses it in writing, listing both as not supported (Google Ads Help).
So a Discover ad cannot take the lead in the feed. The click lands on your own page, and the lead or the call happens there. That is fine, as long as you have wired the tracking to see it. If you have not, the lead is real and the account shows nothing.
We covered the full version of this in the Demand Gen guide and in the Display-to-Demand-Gen migration piece. The short version: buying Discover buys you reach, and the capture is still your job.
How a Discover lead actually gets counted
Step 1
Discover ad (Demand Gen)
Sitelinks only. No lead form asset, no call asset.
Step 2
Click lands on your page
The form fill or call happens on your own site, not in the feed.
Step 3
Counted only if wired
Dynamic number insertion plus offline conversion import, or the lead is invisible.
Earn vs buy the Discover surface
Both routes get you onto the same feed. They are not the same deal. Here is the trade-off as we run it, for a lead-gen operator deciding where the budget goes.
| Decision | Earn it (organic Discover and AI answers) | Buy it (Demand Gen ads) |
|---|---|---|
| Capture mechanism | Reader lands on your page from a chosen source; you own the form and the call | No lead form and no call asset, both listed as not supported (Google Ads Help); capture happens on your page either way |
| Measurement | Standard organic and referral tracking on your own page | Blind unless you wire dynamic number insertion and offline conversion import; nothing is captured in the ad itself (Google Ads Help) |
| Targeting control | You do not pick the reader; the reader picks you via Preferred Sources (Google) | You buy by selection, not exclusion, so quality drift is hard to steer out |
| Regulated verticals (health, insurance) | Open; content ranks and gets chosen regardless of category | Constrained; sensitive categories cannot use advertiser-curated audiences and serving may be restricted, only predefined Google audiences remain (Google policy) |
| Cost and commitment | Content cost, paid once, compounds over time | Media cost, paid every day, stops when the budget stops |
| Durability | A chosen source stays chosen until the reader changes it | Presence ends with the campaign |
The honest read: neither wins everywhere. Earn it when your vertical is regulated, when your content is strong enough to be chosen, or when you want a position that outlasts the media budget. Buy it when your vertical is open, your landing page already converts, and your tracking is wired well enough to see what the reach actually produced.
What to do this week, by vertical
You do not need to reorganize the account over this. You need to do a few specific things.
- Earn the slot first. Add the Preferred Sources button to your best pages and keep publishing content a reader would choose. This is the lever that improves with the update, and it costs no media.
- Check your capture before you scale Demand Gen. Confirm dynamic number insertion is live and offline conversion import is feeding closed outcomes back to Google. If either is missing, fix that before you raise the budget.
- Lean on the earned surface for health and insurance. For U65 and ACA, sensitive-category rules take advertiser-curated audiences off the table and Demand Gen serving may be restricted, so the paid option is boxed in and the reliable play is earning the slot (Google policy). Our health-insurance leads breakdown covers how that vertical actually sources.
- Do not reallocate budget to buy your way onto Discover. The surface got more valuable to earn, not more buyable. Spend the effort on the content and the tracking, in that order.
Frequently Asked Questions
Can I run ads inside Google Discover?
Yes, through Demand Gen, which is the campaign type that serves Discover, Gmail, and YouTube. It carries sitelinks only (Google Ads Help), with no lead form asset and no call asset (Google Ads Help). The ad drives the click; the lead or call is captured on your own page.
Does the update change my Demand Gen targeting?
Not the mechanics. You still buy Demand Gen by selecting audiences, not by excluding placements. The personalization update changes the reader’s side of the feed, not the advertiser controls, so the interest graph gets richer while your ability to steer quality stays the same.
Is Google Discover available for health insurance ads?
As a paid channel it is heavily constrained. For sensitive categories like health, advertisers cannot use advertiser-curated audiences such as Customer Match or lookalikes, and Demand Gen campaigns may be restricted from serving; only predefined Google audiences like in-market and affinity remain (Google policy). You lose the targeting that made paid worth buying, so for health and insurance treat Discover mainly as an earned, organic surface.
How do I measure leads from Google Discover?
On your own page. A Demand Gen ad cannot capture the lead in the feed, since it has no lead form asset and no call asset (Google Ads Help), so you rely on dynamic number insertion for calls and offline conversion import for closed outcomes. Wire both before you spend, or the account will show blanks where the leads are.
Where this leaves you
Discover got more personal, and the personal feed rewards the source a reader chooses. For a lead buyer that is good news you collect by earning, not by bidding. Get the content chosen, wire the tracking, and keep paid Discover in its lane.
If you want a second set of eyes on where your lead budget should sit across paid and earned, that is what we do.
