Google Ads is changing bidding for budget-limited campaigns
From August 17, 2026, Google Ads is changing how campaigns that are limited by budget and use a target-based bid strategy (Target CPA or Target ROAS) behave. These campaigns will now perform more consistently toward the set target, even when budgets are adjusted. Google will not adjust targets or budgets automatically; the responsibility is on the advertiser. The Bid Target Adjustment Tool went live on July 6 to help prepare.
A new balance in target-based bidding
Google announced a change to target-based bid strategies effective August 17, 2026. The change covers Search, Shopping, Performance Max, Demand Gen and Travel campaigns. Campaigns managed in Search Ads 360 and Demand Gen campaigns in Display & Video 360 are also included. App, Video Reach and Video View campaigns are out of scope. In short, this is a structural adjustment that touches most standard conversion and sales-focused campaigns.
What happens today, what changes after August 17
Today, a campaign that is "Limited by budget" and uses Target CPA or Target ROAS can often perform above its target, that is deliver conversions cheaper than the target, but results can fluctuate when the budget changes. After August 17, these campaigns will perform closer to the target and more predictably.
Google's example is clear: if your Target CPA is 10 units but your recent actual CPA is 5, the campaign will start delivering closer to a 10-unit CPA. An advertiser who wants to keep current performance should lower the target to 5, or to another value that fits their business goal. Google explicitly states it will not change targets or budgets on its own; reviewing the account by August 17 and adjusting campaigns, especially those performing better than target, is the advertiser's responsibility. To make this preparation easier, the Bid Target Adjustment Tool went live on July 6, 2026; it shows historical performance and lets you apply target updates quickly.
A technical-looking setting, a direct hit on budget efficiency
The change looks technical but affects budget efficiency directly. Campaigns performing below target, that is delivering conversions cheaper than expected, may drift up toward the target after August 17 if nothing is done; that can mean fewer, on-target conversions for the same budget. Conversely, for the advertiser who sets targets deliberately, the system becomes more consistent and predictable. In short, this is a "check and adjust," not a "set and forget," change; the difference will be made by those who review their accounts before the deadline.
What it means for businesses in Türkiye
In Türkiye, small and mid-sized businesses often run Google Ads campaigns that are limited by budget, which puts them right at the center of this change. Businesses that do not review their accounts by August 17 and do not update targets on their well-performing campaigns may see their cost per conversion quietly rise. Those who act early and adjust Target CPA and Target ROAS to actual performance will keep the efficiency they get from the same budget. In a market where a limited budget must be managed even more carefully, not missing a threshold like this is a direct profit-and-loss matter.
The UNALSOFT take
Our approach to ads is already "check and adjust," not "set and forget": we set targets against business outcomes and manage campaigns with regular measurement and tuning. In our ad management service we put platform changes like this on the calendar and prepare accounts ahead of thresholds such as August 17, because a bid-strategy change, if not managed well, can quietly erode the result you get from the same budget. Turning change into opportunity is possible through measurement.
Rules change, discipline pays off.
Let's prepare your campaigns for the August 17 change and protect your budget's efficiency together.
