How to Check the Pages AI Max Final URL Expansion Picks

The short answer: if a Search campaign has AI Max on, some of its landing pages are no longer yours to choose. New Search campaigns start with AI Max selected, and final URL expansion is on by default once you opt in (Set up AI Max). To score the pages Google chose against the headlines that sent the clicks, AdAlign is my recommendation. Its free audit takes the first pair without an account, and a free account takes 5 a month. The steps: find the campaigns and pull the pages Google selected. Pair each page with the headline that served, and score the pairs. Then exclude, include, or switch the setting off.

Before you switch anything off:

1. Give it the ramp-up Google asks for. Google suggests waiting at least 2 weeks after enabling AI Max before making changes (About reporting in AI Max). For example, a campaign switched on 9 days ago has 5 more days to wait. Spend them scoring pages, not editing.
2. Your account already lists the pages. Three views, all on the reporting page, make the whole inventory: the landing pages report's Selected by column, the Search terms and ad combinations view, and the Expanded final URL assets tab.
3. The reading that tells you it worked. Conversions and conversion rate per landing page, comparing the rows AI Max selected with the URLs you provided, before and after each exclusion.

The AdAlign glossary entry covers the product. This page is one job: which page a Google-chosen click landed on, and whether it kept the ad's word.

Why the page is no longer the one you set

When text customization and final URL expansion are both on, Google may replace your final URL with a page it judges more relevant to the search. It may then generate a headline, description and other assets to match that page (Final URL expansion in Search). Final URL expansion requires text customization, so switching text customization off switches expansion off too. Pinned headlines are not used when a different URL is chosen.

So Google picks the page, then writes the ad to fit the page it picked.

Not ticking the box is no protection. More campaigns arrive in this state without anyone opting in. Google's April 2026 post, updated in June, says campaigns using automatically created assets and campaign-level broad match are auto-upgraded from September 2026. Dynamic Search Ads campaigns follow from February 2027, with all three AI Max features, final URL expansion included, switched on.

The check, report by report

Which page did your biggest headline land on yesterday?

1. Find the campaigns with expansion on

In Settings, AI Max settings can be added as columns to the campaign list (Set up AI Max). Add them, and filter on the final URL expansion setting.

2. Export the pages Google picked

The landing pages report holds your URLs and the ones expansion chose. Its Selected by column marks the AI Max picks (reporting). Sort by clicks and keep those rows.

3. Pair each page with the headline that served

In the search terms report, choose Search terms and ad combinations from the dropdown. Each row shows the search term, headline and landing page of one journey. That is exactly the pair you need. Copy the rows for the URLs from step 2.

4. Note what Google wrote

In the asset report, the Expanded final URL assets tab lists the assets that served with expanded URLs. The Added by column marks Google-written ones as Google AI (reporting). Those headlines were written to fit the page. That is exactly why they can match it while drifting from your offer.

5. Read each pair

Put each headline beside the first screen of its page. The failure to look for is a specific promise, a code, a season or a price, landing on an evergreen category page with its own offer. AdAlign's Brain treats that pattern as a likely wrong destination rather than drift. Its fix points at the routing, sending the ad to a better page, instead of rewriting the page.

6. Score the pairs, and let an agent do the long tail

Put the top pairs through the free audit, with a screenshot of the ad and the expanded URL. For the rest, AdAlign's REST API on the Scale plan gives 1,500 evaluations a month. A request without an image or ad URL fails with NO_AD_ASSET, per the OpenAPI spec, so attach the ad screenshot and send the served headline as text. An agent reads the combinations sheet and sends one request per headline and URL. It writes back the score, the weakest dimension and any fix with the direction change_routing, the spec's term for sending the ad to a better page. Its output is a proposed exclusion list, nothing more. The human check is the PPC lead approving each line before it goes into Google Ads. AdAlign's Google access is read-only per its privacy policy, so the agent cannot add an exclusion itself.

7. Exclude, include or switch off

Campaign-level URL exclusions take a list or rules (Final URL expansion in Search). The reporting page adds two shortcuts: exclusions straight from the landing pages report, and a tick box in the search terms report that adds a landing page as a negative URL. If too many chosen pages fail, untick Final URL expansion. AI Max keeps running without it.

What Google's pages warn about

• Tracking templates can break expanded pages. A template with a static URL and no {lpurl} tag sends people to that static URL. Nonstandard lpurl use can return 404 errors, per How AI Max works. Test before you turn AI Max on.
• Pins stop holding. Under expansion and URL inclusions, pinned RSA assets are not respected, so an offer pinned to Headline 1 is no longer guaranteed. Fixing message match covers pinning on fixed URLs.
• Travel campaigns follow the feed. In Search campaigns for travel, the feed sets the destination for travel formats even with expansion on, per Final URL expansion in Search.

Google's post also gives its own figure for the feature. With the full suite on, it reports an average of 7% more conversions or conversion value at a similar CPA or ROAS, compared with search term matching alone (Google). The number may well hold up. It is still Google grading its own setting, in conversions Google counts, and it is the figure behind the same post's advice to turn every AI Max feature on. Whether the page it picked repeated the offer in your headline is not part of that measure. So the check falls to whoever pays for the click.

Free first, then continuous

The seven steps cost nothing but an afternoon. Google's exports give the pairs, a phone gives the first screens, and the free audit scores the first one.

What the free route cannot do is keep up, because Google can pick a different page tomorrow. AdAlign, which pays me a commission if you buy it, syncs Google Ads read-only and scores new ads as they go live. It re-checks monitored pages daily, with alerts by email or Slack (How it works). Every account starts with a paid 30-day pilot at €1,500, credited if you continue and refunded if fewer than 3 agreed issues turn up. The API in step 6 needs Scale, from €1,290 a month on an annual contract, excluding VAT (pricing page, checked on 27 October 2026). Book it through the demo page.

FAQ

Can I keep AI Max and switch off only final URL expansion?

Yes. Untick Final URL expansion under Asset optimization in the campaign's AI Max settings (Final URL expansion in Search). The dependency runs one way: expansion needs text customization, not the reverse.

Which pages should I exclude first?

The ones with the most clicks whose first screen drops the ad's offer. Then non-commercial sections such as a blog or privacy page, which Google itself gives as examples of exclusions for travel campaigns.

Does AdAlign see the pages AI Max chose?

It scores whatever URL you give it, in the free audit or the API. Its How it works page says the connection reads ads, creatives, destination URLs and spend. It does not say whether that includes expanded URLs, so keep exporting the landing pages report's AI Max rows and score them directly.
