As of August 17, 2026, Google Ads is changing how budget-limited campaigns running target-based bid strategies work. The goal of the update is to make campaigns track the advertiser’s stated target more consistently, even as the budget changes.
That description sounds benign at first glance. But in campaigns that are currently running more efficiently than their stated target, if the settings aren’t reviewed, actual CPA could rise, actual ROAS could fall, or traffic and conversion volume could fluctuate temporarily.
That’s why Google is notifying affected account owners and recommending that settings be reviewed before August 17, 2026. According to Google’s announcement on the change to target-based bid strategies, the new Bid Target Adjustment Tool will become available on July 6, 2026.
First, Let’s Define the Scope Correctly
The update doesn’t cover every Google Ads campaign or every CPC bid. Two conditions have to be met together for a campaign to be affected:
- The campaign must be in “Limited by budget” status.
- The campaign must use one of the following target-based bid strategies.
| Bid strategy | Affected by the update? |
|---|---|
| Target CPA | Yes |
| Target ROAS | Yes |
| Target CPC | Only in Demand Gen campaigns |
| Manual CPC | No |
| Target Impression Share | No |
| Maximize Conversions without a target | Not directly in scope |
| Maximize Conversion Value without a target | Not directly in scope |
The CPC distinction here matters. The change does not affect Manual CPC. The Target CPC that’s in scope is the automated bid strategy Google offers for Demand Gen campaigns. Google’s official FAQ page draws this distinction explicitly.
The scope covers Search, Shopping, Performance Max, Demand Gen, and Travel campaigns managed through Google Ads or Search Ads 360, as well as Demand Gen campaigns in Display & Video 360. Target CPA and Target ROAS campaigns that aren’t budget-limited won’t see any behavior change from this update.
What Exactly Changes on August 17?
Today, some budget-limited campaigns can deliver an actual result that’s better than the target shown in the panel. For example, a campaign with a Target CPA of 1,000 TL might have been running at an actual CPA of 600 TL over recent weeks. Under the current system, the budget constraint can produce a result that exceeds the target — which looks more efficient from the advertiser’s point of view.
After August 17, the system will track the defined target more closely even as the budget changes. In the same example, if the Target CPA is left at 1,000 TL, actual CPA could move closer to 1,000 TL over time. That doesn’t mean every single conversion will cost exactly 1,000 TL; bid strategies evaluate the target based on the average result.
On the Target ROAS side, the logic runs in the opposite direction. If a campaign’s target is 400% and its recent actual ROAS is 650%, the system may scale closer to the defined 400% target after August 17. That opens the door to more volume, but efficiency could drop from the current 650% level.
Google isn’t changing the auction system with this update. What’s changing is how the automated bidding system interprets the advertiser-entered target in budget-limited campaigns.
Why Does This Change Pose a Risk?
The real risk is that the target shown in the panel and the business’s actual target have drifted apart over time.
An account manager might have left the Target CPA setting at 1,000 TL, reasoning that “the campaign is already delivering 600 TL CPA.” Under the old behavior, that gap may not have always caused a visible problem. Under the new behavior, the system will treat 1,000 TL more consistently as the actual optimization target to work toward, rather than as a theoretical ceiling.
Similarly, in a campaign delivering a high actual ROAS, a target that was left too low can open up more room to move from efficiency toward volume. That’s not necessarily bad for every business. The problem is when this shift is the byproduct of an old setting rather than a deliberate growth decision.
What Should Account Owners Do Before August 17?
1. List the campaigns that will be affected
The status and bid strategy columns should be checked together on the Campaigns screen. Campaigns that have been in “Limited by budget” status within the past 12 months and use Target CPA, Target ROAS, or Demand Gen Target CPC should be pulled into a separate list.
Google plans to show notifications to advertisers who have had a campaign meeting these conditions within the past 12 months. Still, rather than relying solely on the notification, it’s safer to check the entire account, including portfolio strategies and shared budgets.
2. Compare the stated target against actual performance
Don’t look at a single week. Choose a meaningful date range that rules out seasonality, conversion delay, and any major recent changes.
- What’s the gap between Target CPA and actual CPA?
- What’s the gap between Target ROAS and actual ROAS?
- If Demand Gen is in use, what’s the gap between Target CPC and the actual average CPC?
- Do these results align with the business’s profitability threshold?
- Is the campaign outperforming its target purely because of the budget constraint?
Simply matching the target to the historical average isn’t enough. Past performance is a reference point. The right target should be set together with the business’s margin, lead quality, and close rate.
3. Deliberately choose one of three options
If you want to preserve current efficiency: Bring the panel target closer to recent actual performance. For example, in a campaign with a Target CPA of 1,000 TL that’s delivering an actual CPA of 600 TL, if 600 TL is the right level for the business, pulling the target down to that level is worth considering.
If you want a middle ground based on business goals: Even if the result is 600 TL, if the sustainable profitability threshold is 750 TL, the target can be set at 750 TL. That opens room for the system to seek more volume in a controlled way.
If the current panel target is already right: There’s no need to change the setting. But keep in mind that after August 17, the campaign may move closer to the defined target instead of its previous, higher efficiency.
4. Use the Bid Target Adjustment Tool
Accessible via an in-account notification starting July 6, the tool will show historical campaign performance and offer a quick way to update targets. The suggestion inside the tool shouldn’t automatically be taken at face value. The recommended value should be compared against actual profitability and sales quality.
Google will not automatically change targets or daily budgets on the advertiser’s behalf. Clicking “Apply” or making a manual adjustment will remain the account owner’s decision.
5. Set up a post-change measurement plan now
Google recommends waiting 1–2 conversion cycles to evaluate performance after a target change or system transition. In B2B accounts with long sales cycles, that period can run much longer than a few days.
The official FAQ also notes that temporary inconsistencies may appear in budget and bid estimates between August 17 and 31. Making another big adjustment based on a single day’s CPA or ROAS movement during this window can make measurement even harder.
Do You Have to Increase Your Budget?
No. The update won’t automatically raise your budget. Daily and monthly spending caps stay in place. Google’s approach is to make it possible to grow the budget more predictably once the right target is set.
Accounts that don’t want to raise their budget can still adjust their targets based on business outcomes. If maximizing conversion volume within a fixed budget is the priority, target-free strategies like Maximize Conversions or Maximize Conversion Value can also be considered — though under these strategies, actual CPA or ROAS can swing more as the budget changes.

What Not to Do
- Changing every campaign’s target by the same percentage just because a notification arrived.
- Bulk-editing Manual CPC campaigns as if they were affected by this update.
- Trusting the panel’s CPA or ROAS figure alone without verifying conversion tracking first.
- Ignoring conversion delay and seasonality when reviewing historical performance.
- Adding data exclusions or new bid limits because of the update.
- Changing budget, target, conversion action, and campaign structure all at once, making the result impossible to measure.
In particular, check the primary and secondary status of your conversion actions. Even a flawlessly running Target CPA or Target ROAS strategy can optimize for the wrong outcome for the business if it’s built on an incorrect or low-quality conversion signal. The Google Ads conversion tracking guide can help with this check.

Quick Take
This update raises the stakes on “what’s written in the panel” for target-based bid strategies. In the past, a campaign outperforming its target could mask the fact that an incorrect or outdated target had been sitting in the account unnoticed. After August 17, the gap between the stated target and the expected business outcome will feed through to performance more directly.
So the right move isn’t to automatically lower targets or raise budgets. First figure out which campaigns are genuinely in scope, then tie the target to the business’s acceptable cost and return threshold — not to a historical average.
