AI Max Turn 1 for Lead Gen: The Pre-Migration Setup That Stops Google From Burning Your First $10K

Google’s AI Max “Turn 1” announcement is being read across the trade press as a win for advertiser control. For lead-gen accounts, the framing is misleading. The new steering levers are guardrails that prevent waste. They are not optimization knobs that drive performance, and treating them like Performance Max asset groups will tank lead quality fast.

If you run paid acquisition for insurance, mortgage, home services, financial services, or B2B lead gen, this AI Max for Search migration guide for lead generation is built around one operational truth: the first 14 days of post-migration learning decide the next 12 months of unit economics. The window to set guardrails is now, before Google migrates your Dynamic Search Ads spend automatically.

Here’s what actually changed, what didn’t, and the exact setup to run this week.

Turn 1 Shipped Four Steering Controls, and None of Them Are Optimization Levers

The Turn 1 update added four steering controls worth knowing by name.

Brand inclusions and exclusions let you tell AI Max which brands your ads should and should not appear against. For affiliate and lead-gen accounts that can’t legally bid on partner brands, or insurance accounts that need to stay off competitor carrier names, this is table stakes. It does not, however, prevent every gray-area query, only the brand-mapped ones Google recognizes.

Locations of interest separates physical-presence targeting from search-intent targeting. A user in Ohio searching “final expense quote Texas” can now be excluded if you only sell in Texas. For geo-licensed verticals, this single toggle prevents a meaningful chunk of waste.

URL inclusions and exclusions control which pages on your domain are eligible to receive AI-routed traffic. We’ll come back to this. It is the most important lever in the entire update.

Expanded reporting on AI-generated headlines and search terms gives you a partial view of what the system is doing on your behalf. Partial. You see categories and examples, not every query.

What’s missing matters as much as what shipped. There is still no granular match-type control inside AI Max. There is no true keyword-level negative list at the AI Max level the way DSA had page feed negatives. And there is no creative-level steering. You can give the system signals, but you cannot tell it “never write a headline that implies free service.” For verticals with compliance exposure, that gap is real.

For official scope and current limitations, work from Google’s AI Max for Search documentation directly rather than secondary coverage. Google’s own naming has been inconsistent across the rollout, so cross-reference the Help Center against the Google Ads blog announcement before you make migration decisions.

The DSA Auto-Migration Carries Settings, Not Smart Bidding Memory

Google has signaled that new Dynamic Search Ads campaign creation ends in 2026, with full DSA sunset following. Existing DSAs get absorbed into AI Max for Search. We covered the timeline in detail in the AI Max migration deadline breakdown.

Here’s the part most operators miss. Some settings carry over. Smart Bidding learning does not.

What carries: page feeds, negative keyword lists, location targeting, language settings, conversion actions tied to the campaign. What resets: the Smart Bidding model’s understanding of which traffic converts. Post-migration, the bidder enters a fresh learning phase, and it learns against AI-expanded traffic, not the tighter DSA traffic it was previously trained on.

That fresh learning phase is the trap. Smart Bidding anchors on whatever conversion signals fire during the early learning window. If the signals are clean, qualified leads only, the algorithm pursues that pattern. If the signals are dirty, the bidder learns to find more of the same junk, and the cost to retrain it later is higher than the cost of getting the launch right.

We’ve watched this dynamic play out across previous Google Ads platform shifts. Smart Shopping to Performance Max in 2022 was the closest analog. Across the final-expense and Medicare accounts we audited post-migration, CPLs initially dropped 20-30% while lead-to-sale rates quietly collapsed by half over 60 days. Two to three months of retraining later, those accounts were back to baseline. The same pattern is set up to repeat with AI Max.

URL Expansion Is the Single Most Important Lever, and Almost No One Is Writing About It

Here is the operator-level insight that matters most.

AI Max routes paid traffic to any indexed URL on your domain by default. That includes pages you never intended to use as ad landing pages.

The failure mode is fast and brutal. A /thank-you confirmation page gets surfaced by AI Max. A user clicks an ad, lands on the thank-you page, and the conversion pixel sitting on that page fires on the visit itself. Smart Bidding sees a 100% conversion rate on that URL. Within 72 hours, the bidder is optimizing toward whatever cheap clicks happen to land on /thank-you, which is exactly the junk traffic you don’t want.

The same pattern shows up with:

• /careers and /jobs pages, which trigger on employment-intent searches and have no commercial value
• Blog category archives like /blog/medicare-tips/, which surface for top-of-funnel queries that don’t convert
• Gated PDF download URLs, where the “conversion” is a content download, not a lead
• State-specific landing pages outside your licensed geos
• Login portals, account dashboards, and customer-only URLs
• Old promotional pages from expired campaigns

The fix is the URL exclusion list, and ideally the inclusion-only mode if your site has more than 50 indexed pages. Inclusion-only flips the logic: instead of excluding bad URLs one at a time, you tell AI Max “only these pages are eligible.” For lead-gen accounts with five to fifteen real landing pages, inclusion-only is the safer default.

Lock the exclusion list before the migration runs, not after. The first 14 days of post-migration learning are what the algorithm anchors on, and retraining costs more than prevention.

Your Pre-Migration Checklist: Five Setup Moves to Run This Week

Five concrete moves. Execute in order.

1. Build the URL Exclusion List, or Switch to Inclusion-Only Mode

Pull a crawl of every indexed URL on your domain. Screaming Frog or a Search Console export both work. Flag every URL that is not a paid landing page. That is your exclusion list.

If you have more than 50 indexed pages, switch to inclusion-only mode and list only the URLs you actually want AI Max to serve. Faster, safer, harder to break.

2. Add Brand Exclusions for Competitors and Partners

For affiliate and lead-gen accounts: add every partner brand you can’t legally bid on. For direct advertisers: add every competitor brand you don’t want to show against, plus any brand-adjacent terms that have produced low-quality clicks historically.

This is also where you protect against AI-generated headlines that drift into compliance gray areas. A brand exclusion does not catch creative drift, but it does prevent the worst auction matches.

3. Tighten Locations of Interest for Geo-Licensed Verticals

If you sell insurance, mortgage, or any product that requires state-level licensing, set locations of interest to physical-presence-only for licensed states. Do not let “interest” matching surface searches from outside your footprint just because the query mentions a licensed state.

For home services with hard service-area boundaries, the same logic applies. A roofing contractor in Phoenix should not be paying for clicks from someone in Tucson searching “Phoenix roofing.”

4. Audit Your Conversion Actions Before, Not After, Migration

This is where most accounts get killed. If your conversion actions include soft signals (form views, page scrolls, video plays, PDF downloads), Smart Bidding will optimize toward whatever produces those soft signals at the lowest cost. After migration, that means cheap junk traffic that scrolls a page.

Demote or remove every soft conversion. Keep only:

• Submitted lead forms with verified contact info
• Qualified phone calls (90 seconds or longer, with proper call tracking in place)
• Booked appointments or closed sales fed back via offline conversion imports

In our experience running insurance and HVAC accounts, calls under 60 seconds qualify at under 10%, which is why we set the inbound qualification threshold at 90 seconds before a conversion fires back to Google Ads. If you’re not already feeding offline conversions back, the AI Max migration is the forcing function to fix it. The bidder needs revenue-quality signal, not form-fill volume. We’ve covered the mechanics of revenue-based attribution in detail.

5. Cap Budget and Daypart Aggressively for the First Two Weeks

Set a hard daily budget cap at 60-70% of your normal spend for the first 14 days post-migration. Daypart to your call center hours or your highest-converting historical windows. The goal is not maximum volume during learning. The goal is clean signal.

A contained learning window is recoverable. A runaway learning window with bad anchors takes months to retrain.

Watch These Four Signals in Weeks 2-6 to Catch AI Max Learning on Junk

Post-migration monitoring is its own discipline. The metrics that look good can hide the metrics that matter.

The diagnostic pattern to watch for: CPL drops while lead-to-sale rate falls faster. That combination means the bidder is finding cheap traffic that doesn’t close. CPL alone will tell you the migration is going well. Revenue per lead will tell you it isn’t.

Use the maximum profitable CPL formula to stay honest:

Maximum profitable CPL = gross profit per customer × lead-to-sale conversion rate

If your gross profit per customer is $400 and your historical lead-to-sale rate is 18%, your max profitable CPL is $72. If post-migration CPL drops to $48 but lead-to-sale rate falls to 9%, your real max profitable CPL is now $36, and you’re losing money on every lead that looks cheap on the surface.

The other diagnostic signals:

• Search term reports surfacing irrelevant queries. Pull weekly. Add negatives weekly.
• Top landing pages showing thank-you, careers, or non-commercial URLs. Pause immediately and rebuild the exclusion list.
• AI-generated headline reports showing copy that misrepresents the offer. Especially relevant for compliance-regulated verticals. Document and submit feedback through your Google rep.
• Sudden volume spikes with no corresponding lift in qualified leads. Almost always a signal that AI expansion has found a low-quality query cluster.

Kill-switch criteria: if lead-to-sale rate drops more than 30% from your pre-migration baseline within 21 days, pause the campaign, rebuild exclusions, reset the conversion window, and relaunch with tighter guardrails. Do not try to optimize through it.

For accounts also dealing with the 37-month data cap that takes effect in June 2026, get your BigQuery archive live before migration so you have pre-migration baselines to compare against. You will need them.

Frequently Asked Questions

When does Google start auto-migrating DSA campaigns into AI Max?

Google has indicated that new DSA campaign creation ends in 2026, followed by a full sunset of existing DSA campaigns into AI Max for Search. Specific account-level migration dates are being staggered. Check your Google Ads notifications and the official Help Center for your account’s migration window, and assume you have weeks, not months.

What’s the difference between AI Max steering controls and Performance Max asset groups?

Performance Max asset groups are inputs the system uses to generate and place ads across Google’s full inventory. AI Max steering controls are exclusion-based guardrails: brand exclusions, location-of-interest filters, and URL inclusion/exclusion lists. You feed creative to PMax. You restrict surface area in AI Max. Treating them the same way is the fastest path to wasted spend.

Can AI Max really route traffic to any URL on my domain?

Yes. By default, AI Max for Search treats your full indexed domain as eligible landing-page surface, similar to how DSA page feeds worked but broader. The exclusion list (or inclusion-only mode) is what restricts that behavior. If you don’t configure it, expect traffic to surface against thank-you pages, blog archives, careers pages, and any other indexed URL.

How do I know if Smart Bidding has anchored on bad signal post-migration?

The two diagnostics that catch it fastest: the Top Landing Pages report (any non-commercial URL in the top 10 by spend is a red flag) and the gap between CPL and lead-to-sale rate. If CPL drops while sale rate drops faster, the bidder is finding cheap junk. Pull both reports weekly for the first six weeks.

Do I still need page feeds after migrating to AI Max?

Page feeds carry over from DSA and still function as a signal in AI Max. They’re not a substitute for URL inclusion/exclusion lists, though. Use both: page feeds tell AI Max which pages to prioritize, while exclusion lists tell it which pages are off-limits entirely.

Should I migrate proactively or wait for Google’s auto-migration?

Proactive migration gives you control over the timing and the guardrail setup. Auto-migration runs whenever Google decides, often without warning aligned to your launch calendar. For any account spending over $10K/month on DSA, proactive migration with full pre-launch guardrails is the lower-risk path.

Talk to Our Team Before Google Migrates Your Account

For advertisers buying or generating leads at volume in regulated verticals, the AI Max migration window is short and the downside is real. We’ve run paid acquisition through every major Google Ads platform shift since the Smart Shopping to Performance Max transition, and the pattern is consistent: the accounts that lock guardrails before migration day outperform the accounts that try to fix problems after by a wide margin.

If you’re running insurance, mortgage, home services, financial services, or B2B lead-gen volume and want a second set of eyes on your pre-migration setup, we can walk through your URL exclusion list, brand controls, conversion actions, and the migration plan specific to your vertical.
