This story first broke on July 6, 2026.
Starting August 17, 2026, Google Ads changes how it handles campaigns that have been quietly beating their own targets. If that’s been happening on your account, your cost per result is about to go up unless you act first.
What to Check
1. In Google Ads, look for a notification pointing you to the new Bid Target Adjustment Tool.
2. Check any campaign using Target CPA or Target ROAS that shows a “Limited by budget” status.
3. Compare your set target to your actual recent performance. If your actual cost is lower than your target, that gap is about to close.
What’s Changing in Google Ads
Right now, a budget-limited campaign using a target-based bid strategy can perform better than the target you set, delivering results at a lower cost than you told Google to aim for. After August 17, Google’s bidding system will stop allowing that gap to persist. Campaigns will shift towards hitting the number you entered, not beating it.
In Google’s own example, a campaign with a ten dollar Target CPA that’s been quietly running at five dollars will start moving toward ten dollars once the change takes effect. Nothing about the ad or the product changes, the cost per result does.
What to Do About It
Google gives four real options: leave the target as-is and accept the shift, lower the target to match what the campaign has been achieving, set a custom target based on real business goals, or switch to a bid strategy that doesn’t use a fixed target at all. Google will not make any of these changes automatically. Whatever a campaign is set to today is what it carries into August 17 unless someone changes it first.
This is easy to miss if nobody’s reviewing account settings regularly. Having someone check current bid targets against actual performance before the deadline is the difference between a planned adjustment and a surprise cost increase.
