Google Ads quietly handed you back three controls

If you spend money on Google Ads, some of it is almost certainly going to searches that have nothing to do with your business. For two years Performance Max, Google's all-in-one automated campaign type, gave you no way to see that waste, let alone stop it. You set a budget and a goal, handed Google your ads, and hoped. That changed. Through 2025 and into 2026 Google added back three real controls. None were announced loudly. All of them save you money. Here is what each one does.

What changed

Three things, in order of how much money they save you.

You can add negative keywords to Performance Max. A negative keyword is a search you tell Google never to show your ad for. If you install home solar panels, "solar phone charger" is a negative. These rolled out to every advertiser in January 2025, and Google later lifted the cap far past the old 100-keyword ceiling. Before this, Performance Max could spend on searches you would never choose, and you could not stop it. Now you can. (Search Engine Journal has tracked the rollout.)

You can block placements across your whole account. A placement is any website, app or video where Google puts your ad. As of early 2026, one central exclusion list blocks bad placements everywhere: Performance Max, Demand Gen, Display and YouTube, which are Google's different ad formats across the web and video. This came after independent researchers showed Google ads turning up on junk sites and worse, which pushed Google to show advertisers exactly where each ad ran, starting March 2025. (eMarketer covered the transparency push.)

You can see the search terms. Performance Max now has a search terms report: the list of actual searches people typed before your ad appeared. Thinner than the version regular Search campaigns get, but it finally shows what you are paying for. That is the single most useful place to look when a campaign is burning budget with little to show.

A fourth change is coming whether you act or not. AI Max for Search is Google's new AI layer for regular Search campaigns. It lets Google match your ads to searches you never listed and write headlines for you, and it is replacing Dynamic Search Ads (the older version of the same idea). The forced migration was pushed to 2027, but new Search campaigns lean on it by default. (Google's own announcement lays out the features.)

Why it matters

Automation did not go away. Google still decides how much you bid, where your ads run and mostly who sees them. What changed is that you can now see what it did and fence off the worst of it. That is the difference between a black box and a machine you supervise.

The biggest leak is your own name. A long-running complaint is that Performance Max quietly spends on searches for your own business, people typing your name who would have found you anyway, then takes credit for those sales. It makes the campaign look brilliant and hides the fact that it may be finding you very few genuinely new customers. The specialists at Optmyzr studied tens of thousands of campaigns and the pattern repeats. It is the same blind spot that haunts a search powered by AI Overviews: the system answers for you and you lose sight of what it is doing.

The placement and search-term controls matter for a simpler reason. A small budget cannot afford waste. A fifth of your spend on irrelevant searches is a fifth not reaching a buyer.

Your move

Spend twenty minutes in your account and do these in order.

1. Pull the search terms report. Find searches that have nothing to do with what you sell. Every junk theme becomes a negative keyword. Repeat monthly. A research tool like Semrush helps you spot recurring junk patterns and the buying-intent searches worth keeping.
2. Set your brand straight. Run a separate, cheap campaign for your own name and tell Performance Max to exclude those searches. Now your numbers reflect real new-customer hunting.
3. Build one account-level placement exclusion list. Block the obvious junk sites once, and it protects every campaign. Check the placement report after a couple of weeks.
4. Decide on AI Max deliberately. If you rely on Dynamic Search Ads, turning AI Max on yourself now means you set the brand and website settings on your terms. Waiting means Google flips it for you on its timeline.

The ad gets you the visit. What happens after the click decides whether the spend pays off. If a click lands on a page with no clear next step and no follow-up, the budget you just protected leaks out the other end. Lead-capture tools like GoHighLevel exist for that gap, and the principle holds with any setup: catch the enquiry and respond before the person cools off. The same logic runs through email deliverability in 2026, where a follow-up only counts if it actually lands in the inbox.

Worth watching

Two things to keep an eye on.

Whether Google adds budget control to match its reporting. Performance Max shows you how spend split across its channels, but still will not let you set a budget per channel. Reporting without control is half a gift.

The AI Max migration. Deadlines have already slipped once, from 2026 into 2027. If you run Search campaigns, treat the migration as a when, not an if, and get familiar with the brand inclusion and exclusion settings before it is forced. Both big ad platforms are drifting the same way, so it is worth reading our Meta Advantage+ briefing alongside this.
