AI Max for Search Campaigns Explained
What AI Max changes in a Search campaign, when it helps lead generation and how to keep control.
Key Takeaways
- AI Max for Search adds broader matching, keywordless matching, automatically adjusted ad text and final URL expansion to a normal Search campaign.
- It can find valuable searches your keywords miss, and it can also match loosely related searches and send people to the wrong page.
- For lead generation, turn it on only once conversion tracking reports qualified leads, then review search terms and landing pages weekly for the first month.
- Dynamic Search Ads are moving into AI Max, so accounts using them will need to review AI Max settings.
On This Page
AI Max for Search is worth testing in a lead generation account once conversion tracking counts qualified leads, because it reaches searches your keyword list misses and adapts ad text to each search. It needs closer supervision than a standard campaign: review its search terms and the pages it sends people to every week for the first month, and exclude pages that should never receive ad traffic. Without accurate tracking, it tends to find cheap clicks and form fills that never become customers.
What AI Max Changes
AI Max is a setting you switch on inside an existing Search campaign. When it is on, it adds:
- Search term matching that reaches searches related to your keywords and your website content, including searches no keyword covers
- Text customization that adjusts headlines and descriptions to match each search, drawing on your site and ads
- Final URL expansion that can send people to the page on your site Google judges most relevant
Your keywords, exact-match keywords in particular, keep working as before. AI Max adds reach on top of them.
Where It Helps Lead Generation
Service businesses rarely build a keyword list that covers every way people describe a problem. A plumbing company may bid on "water heater repair" while customers search "no hot water in shower". AI Max can find those searches. Accounts with strong service pages, clear conversion tracking and enough budget tend to benefit most.
Where It Goes Wrong
- Matching to job seekers, students or do-it-yourself searches
- Sending ad traffic to blog posts, careers pages or service pages for work you do not want more of
- Writing ad text that promises something you do not offer
- Learning from low-quality form fills when every submission counts as a conversion
Reports and Controls
Google's updated AI Max documentation adds reporting on search terms and landing pages and options to exclude underperforming search terms or URLs (Search Engine Land). Use them as follows:
- Search terms. Review weekly at first, then every two weeks. Add negatives for clearly irrelevant searches.
- Landing pages. Check which URLs AI Max chose. Exclude pages that should not receive ad traffic.
- Ad text. Review generated text for accuracy and remove anything that misrepresents your services.
- Brand settings. Set brand inclusions or exclusions where relevant.
Effect on Dynamic Search Ads
Google is moving Dynamic Search Ads into AI Max. If you use Dynamic Search Ads today, record their performance by landing page before the transition, then review AI Max's search terms and page choices closely afterward. Our Google Ads updates page tracks the migration timing.
Running a Fair Test
Use a campaign experiment so AI Max runs against the same campaign without it, with traffic split between them. Run it for at least four weeks and judge on cost per qualified lead and cost per customer alongside the conversions Google reports.
When to Switch It Off
Turn AI Max off in a campaign if, after a month of exclusions and reviews, cost per qualified lead remains clearly higher than the campaign without it, or if it keeps sending traffic to pages you cannot exclude effectively.
