Paid Advertising

Google started moving Search campaigns to AI Max on September 1. Here is what actually changes.

Three changes landed on Google Ads accounts this quarter and none of them asked permission. If you run lead generation for a trade or home services business, the third one is the one that can quietly cost you money.

Key findings

  • September 1 eligible Search campaigns began auto-migrating to AI Max, which broadens matching beyond your keyword list.
  • September manual language targeting was removed from Search campaigns. Matching now reads your ad copy and landing pages instead.
  • All surfaces Limited Ad Serving expanded from Search to YouTube, Gmail, Play and Demand Gen, with throttling applied at account level.
  • User reports carry real weight in that decision. Persistent complaints can get an account classed as unqualified.
  • 37 months is the new retention window for sub-monthly reporting granularity, down from indefinite.

AI Max is the headline, but it is not the risk

AI Max broadens how Google matches your ads. Instead of serving strictly against the keywords you chose, it reads your ad copy, your landing pages and the intent behind a query, then decides whether you are a fit. For a broad ecommerce catalogue that is often a gain. For a contractor bidding on a narrow set of high-value local terms, it is a much bigger deal, because the difference between a kitchen remodel lead and a cabinet-hinge search is the entire margin.

The migration started on September 1 for eligible campaigns. You can still control it, but the default moved, and defaults are what most accounts run on.

Alongside it, Google removed manual language targeting from Search campaigns. Matching is now inferred from the language of your ad copy and landing pages. If you serve a bilingual market, and much of Orange County is, that is worth checking rather than assuming.

Limited Ad Serving is the one to actually worry about

Limited Ad Serving used to be a Search and Shopping concern. It now covers every surface Google sells: YouTube, Gmail, the Play Store and Demand Gen included. When an account is classed as an unqualified advertiser, impressions get throttled at account level rather than campaign level.

The part most advertisers miss is how that classification gets made. Google weighs user reports heavily. Persistent complaints about your content, your products or your conduct can move you into that bucket, and nothing in your campaign settings will tell you it happened. You just see volume fall.

For a home services business, this is a reputational problem wearing an advertising costume. Review management and ad performance are now the same job.

The terms changed too, and they are broader than they look

The Advertising Program Terms were rewritten effective July 1. They now spell out how advertiser-provided inputs can be used across Google Ads features. That covers what you type into conversational setup tools, the URLs you hand over for automated campaign creation, and website content Google accesses when you authorise crawling.

Separately, from July 13 Google began rolling out tools for identifying and labeling AI-generated ad creative. If you are producing creative at volume with generative tools, that labeling is coming whether or not you opt into it.

What we changed in client accounts

For trade and home services accounts, we treat AI Max as something you qualify into, not something you inherit. That means tightening negative keyword lists before broad matching gets a say, and splitting high-intent service terms away from research terms so a single budget is not funding both.

We also moved review monitoring into the weekly ad review. Limited Ad Serving makes reputation an account-health metric, and the first sign of trouble is a volume drop with no setting to explain it.

And we pulled historical reporting out before the retention window closed. Thirty-seven months sounds generous until you want a four-year seasonal comparison for a business whose entire year turns on two quarters.

Our take

None of this is a reason to pull budget out of Google. It is a reason to stop treating the account as something you set up once. The controls that mattered in 2024 are being retired, and the levers that replace them sit in your copy, your landing pages and your reputation rather than in the campaign settings screen.
