Google Announces Changes to tCPA and tROAS Bidding

Google Ads has always required a balance between automation and strategy. Smart Bidding keeps getting more sophisticated, but campaign success still comes down to budget planning, conversion tracking, and how closely bidding goals reflect real business objectives. Starting August 17, 2026, Google is changing how it manages bidding for budget-limited campaigns using Target CPA (tCPA) or Target ROAS (tROAS) strategies. The change is designed to create tighter alignment between stated bidding goals and actual results, which means now is a good time to check whether your current targets still reflect what you’re trying to achieve.

What’s Really Changing?

Today, many campaigns with a “Limited by budget” status are outperforming the goals set in Google Ads. An advertiser might set a Target CPA of $10, but Google’s bidding system finds efficiencies within the budget and consistently delivers conversions closer to $5. Historically, that’s looked like a win. But campaigns that significantly beat their configured goals tend to see more volatility when budgets change, since the algorithm has been optimizing to a number that doesn’t match what’s actually in the account settings. Beginning August 17, campaigns that meet the criteria below will start trending closer to their stated targets unless targets are adjusted beforehand. If your Target CPA says $10, expect performance to move toward $10, even if you’ve been getting $5. This is a bidding behavior change only. Google has confirmed that daily and monthly budgets will continue to be respected, so this won’t directly increase your ad spend. It will, however, change how efficiently that spend converts if your targets are out of date.

Which Campaigns Are Affected?

It’s important to note that this change doesn’t affect every campaign in market. Your Google Ads campaign must meet all three conditions:

• Status is “Limited by budget”
• Uses a Target CPA or Target ROAS bid strategy
• Has historically outperformed its configured goal

This applies to Search, Shopping, Performance Max, Demand Gen, and Travel campaigns. It does not apply to App campaigns, Video reach campaigns, Video view campaigns, Manual CPC, or Target Impression Share strategies. For Performance Max and Demand Gen specifically, you may also see shifts in how traffic is distributed across channels as the system re-optimizes toward your stated target.

Google’s Bid Target Adjustment Tool

To help advertisers prepare, Google is rolling out a Bid Target Adjustment Tool inside Google Ads starting July 6, 2026. The tool flags potentially affected campaigns and shows recommended targets based on recent performance, so you can apply the suggestion, set a custom target, or leave things as they are. Google is not changing any targets automatically. The tool is there to help you make an informed decision before August 17.

What Advertisers Should Do Right Now

Start by asking whether your current tCPA or tROAS goals still reflect your business objectives. It’s common to leave a target untouched for months once performance is working, so this is a natural moment to revisit it. For now, it’s absolutely worth checking on the following:

• Do current tCPA goals align with recent acquisition costs?
• Do tROAS goals still support your profitability targets?
• Have budget-limited campaigns been consistently beating their goals?
• Could future growth plans be affected by the new bidding behavior?

The goal isn’t necessarily to change your settings. It’s to make sure the numbers guiding Google’s automation still match what the business is trying to achieve.

Why This Matters for Franchise and Multi-Location Brands

This is a platform update, but it’s also an account management opportunity, and one agencies should get ahead of rather than react to. Some of the strongest-performing campaigns deserve the closest look here, since campaigns that have consistently beaten their targets are the ones most likely to see a noticeable shift once the update takes effect. At Location3, our paid media team has already begun auditing eligible campaigns, comparing configured goals against actual performance, and using Google’s Bid Target Adjustment Tool to flag accounts that may need adjustment before August 17. We also know that local owner-operated campaigns run on tight, carefully managed budgets. Franchisees are weighing ad spend against a long list of day-to-day costs, so efficiency matters more than ever here. As we review eligible campaigns, our focus is on preserving or improving performance while making sure bidding goals reflect what each business actually needs from its media investment.

As we look ahead, Google’s platform keeps moving toward more automation, but automation is only as good as the goals feeding the algorithms. If you’re running tCPA or tROAS bidding, treat this update as a prompt to check your settings, confirm your performance expectations, and make sure your targets still reflect current business priorities before August 17.
