Dynamic Search Ads are on their way out. Google is replacing them with AI Max for Search, a generative layer that activates directly inside your existing Search campaigns and generates part of your headlines and descriptions itself, straight from your page content. The migration timeline is now public, and it affects every account still running DSAs. The real question isn't whether the switch is coming, it's whether you're in control of what this AI is about to say about your business.

What Google announced

AI Max for Search isn't a new campaign type you build from scratch: it's an extension that activates on your existing Search campaigns, combining broad-match targeting with headline and description generation by Gemini, drawn from your actual page content. Google's stated goal is to capture the queries no keyword anticipates, the exact role DSAs played, but now with automatically generated ad creative on top of automatic targeting.

The migration timeline

The migration isn't happening overnight, but it now has a clear timeframe:

⚠️ Google hasn't communicated a hard shutdown date for existing DSAs. What is confirmed is the end of new DSA ad group creation and an automatic migration triggered in February 2027. Waiting for that deadline means experiencing the switch rather than preparing for it.

What actually changes in your campaigns

The biggest difference isn't targeting, which was already largely automated under DSAs, but ad creative. With AI Max, headlines and descriptions are no longer pulled solely from your feed or product pages: they can be generated and assembled by Gemini on the fly, based on the exact query someone typed. That's a real gain in responsiveness, but also a loss of control over the final message shown, unless it's framed properly upfront.

💡 The real question has little to do with the migration itself anymore, that part is settled. It's whether you're in control of what Gemini is about to say about your business in your ads. A vague or poorly structured landing page mechanically produces a vague or poorly structured ad.

How to migrate without losing performance?

1
Audit your current DSAs before switching
Identify which automatic targets and queries are actually performing today, so you have a baseline to compare against after migration.
2
Test AI Max before the automatic switch
Turning it on voluntarily, on a limited scope, lets you see how Gemini rewrites your ads before it becomes mandatory account-wide.
3
Strengthen the raw material Gemini will use
Page titles, product descriptions, the page content itself: the clearer and better structured this material is, the more relevant the generated ads will be.
4
Check the generated ads, not just the results
A solid ROAS can coexist with a brand message that's drifted. Regularly review the actual headline and description combinations being served.
5
Compare before and after over a matching period
Cost per click, conversion rate, share of queries outside your existing keywords: document these to make a clear-headed budget call.

Conclusion

The shift to AI Max is no longer a distant option, it now has a clear deadline running to February 2027. Accounts that migrate now, on their own terms, reach that deadline with comparison data and raw material that's already been optimised. Those who wait for the automatic migration will discover their new ads at the same time as their customers do.

Since Gemini draws directly on your pages to generate ads, the match between what the ad promises and what the page delivers matters more than ever. To go further: Your ad and your landing page: why coherence changes everything.
