Google DSA Is Being Retired: Your AI Max Migration Guide for 2026
Google is retiring Dynamic Search Ads and automatically upgrading existing campaigns to AI Max, starting September 2026 with final migration beginning February 2027. Here is the timeline, what changes structurally, and how to protect your Search coverage.
Google announced in April 2026 that Dynamic Search Ads would automatically upgrade to AI Max, and the upgrade started rolling out in September 2026. If you have a DSA campaign quietly generating cheap branded and long-tail traffic, that campaign is on a deadline whether or not you have read the announcement. This guide covers the timeline, what actually changes structurally, and what you should verify before Google changes it for you.
The Timeline
- April 2026 — Google announces DSA will auto-upgrade to AI Max
- September 2026 — automatic upgrade begins
- February 2027 — final automatic migration begins
- May 2026 — AI Max for Search campaigns goes live at Google Marketing Live
Google now describes AI Max as the next iteration of DSA rather than a separate product line, which is the framing to keep in mind: this is an evolution of the asset-group model, not a brand-new campaign type bolted onto your account.
Why Google Is Doing This
AI Max is the layer Google uses to match a query to a creative rather than only to a keyword. In DSA that matching was done at asset-group level with a single bidding strategy. In AI Max, asset groups carry their own bidding, and the system can route different queries to different creative combinations within the same campaign. Google has reported that advertisers moving from DSA to AI Max see improvements in conversion volume at broadly similar cost per conversion, and that AI Max passed 500,000 advertisers in its first year. Treat those as Google-reported figures rather than a promise for your account.
What Changes Structurally
The migration is not cosmetic. Four things behave differently once your DSA becomes AI Max.
- Asset groups gain individual bidding. You are no longer managing one learning curve for the whole campaign. Each asset group can bid differently, which is powerful but means you have more numbers to watch.
- Creative matching widens. Queries can be served different creative from the same asset group, so asset quality matters more than it did under DSA.
- URL expansion changes. The final URL expansion behaviour differs, which affects crawl budget and landing-page relevance signals.
- Reporting gets more granular. Asset-group level reporting is where the useful optimisation signals now live.
What You Should Not Do
Resist three reactions, all of which are common and all of which make things worse.
- Do not duplicate every DSA campaign into a parallel AI Max campaign. You will split your own data and learn nothing.
- Do not restructure your account during the automated upgrade. Google is already changing things; add variables and you will not know which change caused the result.
- Do not panic-cut budget on a profitable DSA campaign the week it migrates. Volume will move while the asset groups re-learn, and that dip is not evidence the migration failed.
How to Protect Your Search Coverage
The bottom line for most Indian advertisers is that DSA was doing a specific job: catching long-tail and branded queries without a large keyword list. The risk is not that AI Max is worse. The risk is that the asset groups it inherits are thin, and thin asset groups produce thin results after a learning reset.
- Before migration, make sure every asset group has genuinely distinct headlines, descriptions and images rather than near-duplicates
- Check your search terms report and promote the queries that actually convert into branded and high-intent traffic
- Verify your negatives are still relevant. Auto-upgrade carries exclusions forward, but stale negatives accumulate
- Add conversion tracking that survives the asset-group restructure, and confirm offline conversion import is still firing
The Bottom Line
Do not fight the migration, but do not be passive about it either. The campaigns that come out well are the ones where the asset groups were already differentiated. The campaigns that suffer are the ones that let DSA accumulate years of duplicated assets and hoped the auction would keep covering it. If your DSA was working, the upgrade will probably keep working. If it was carrying brand spend it could not explain, the upgrade is the moment that shows up.
Frequently Asked Questions
When are Dynamic Search Ads being retired?+
Google announced in April 2026 that DSA would auto-upgrade to AI Max. The automatic upgrade began in September 2026 and the final migration begins in February 2027. Google frames AI Max as the next iteration of DSA rather than a separate product.
Do I need to manually migrate my DSA campaigns?+
No. The upgrade is automatic. Manual migration is not required, and manually duplicating campaigns during the automated upgrade splits your own data and makes attribution harder to read.
Will my costs increase after moving to AI Max?+
Google reports that advertisers see higher conversion volume at broadly similar cost per conversion. Treat that as a Google-reported average. Your result depends heavily on whether your asset groups have distinct creative, since AI Max matches queries to creative rather than only to keywords.
What should I check before the migration happens?+
Make sure each asset group has genuinely distinct headlines, descriptions and images, verify your negatives are still current, and confirm conversion tracking including offline import survives the asset-group restructure. Thin asset groups are the main reason results dip after migration.
