Google is quietly rewriting how your Search campaigns work — and it’s happening this month, whether you opted in or not. From September 1 to 30, 2026, Google is auto-migrating every Search campaign using Campaign-level Broad Match or Automatically Created Assets into its new “AI Max” framework. If you or your agency runs Google Ads for your business, the Google AI Max migration isn’t a future roadmap item to research later — it’s changing your account right now, and what you do in the next few weeks decides whether it tightens your targeting or quietly drains your budget.
What AI Max actually changes
AI Max folds keyword matching, ad creative generation, and landing-page selection into one AI-driven layer. Instead of matching purely on keywords, it also reads your assets and landing-page content to decide which queries you show up for — a much wider net than a keyword list alone. Google says brand inclusions and exclusions carry over automatically, but “carry over” doesn’t mean “carry over correctly” for accounts that were never audited in the first place.
Do this: before your account gets swept into the September migration window, pull up your brand exclusion and inclusion lists and check they actually reflect who you don’t want to be found for — competitor names, unrelated services, and any city or product line you don’t serve.
Get a real “before” number
Once AI Max is matching more broadly and generating its own creative, it becomes much harder to tell whether a dip or spike in performance is the algorithm working as intended or a campaign quietly going off the rails. Most Indian SMBs we work with don’t have a clean baseline to compare against — they just have a gut feeling that “ads used to work better.”
Do this: before migration hits your account, document current CPA, ROAS, and conversion volume for each Search campaign. Screenshot it if you have to — you’ll want it in three weeks.
Don’t run it open-loop
AI Max performs best with guardrails, not blind trust. Set URL inclusions and exclusions so the system knows which landing pages are eligible, and double-check any AI-generated ad assets for brand voice before they start serving — Google labels these “Google AI” in reporting, so they’re easy to spot. This is exactly the kind of paid-ads housekeeping we cover in our pre-spend ad checklist, and it matters even more once an algorithm is choosing your creative.
Do this: in the first two to three weeks after migration, check the Search Terms Report daily, not weekly. Catch irrelevant matches while they’ve cost you a few hundred rupees, not a few thousand.
What’s next on Google’s timeline
Broad Match and Automatically Created Assets migrate this month. Dynamic Search Ads follow in February 2027, with reminder notices starting mid-January. If your account leans on DSAs, you’ve got a longer runway — use it to plan rather than wait for the same scramble in Q1 2027, as detailed in Search Engine Land’s coverage of the rollout.
The bottom line: AI Max isn’t optional, and treating it as “just another Google update” is how budgets leak. Businesses that audit their exclusions, benchmark current performance, and watch search terms closely through the migration window will come out with tighter, smarter campaigns. Businesses that ignore the notification in their dashboard will find out the hard way when next month’s ad spend report doesn’t add up.
