Google Ads Bidding Changes You Need to Know Before August 17

Introduction

Google Ads continues to change how automated bidding works across several important campaign types. A major bidding change will take effect on August 17, 2026. This change matters most for campaigns that use Target CPA or Target ROAS bidding. Budget limited campaigns could experience different results after Google applies the new bidding behaviour.

Advertisers who currently outperform their targets should review their campaign settings before August 17. If you need help managing complex campaign adjustments, partnering with a dedicated Google Ads PPC agency in Abbotsford ensures your ad spend stays efficient. Google introduced the Bid Target Adjustment Tool to help advertisers identify affected campaigns.

The upcoming bidding change does not automatically change your existing targets or budgets. Instead, Google will make its bidding system optimise more closely toward your stated target. That difference could influence CPA, ROAS, spending patterns, and campaign performance. Understanding this change can help advertisers make informed decisions before the August 17 deadline.

What Google Is Changing on August 17

Google currently allows some budget limited campaigns to outperform their stated targets. For example, a campaign might carry a $10 Target CPA while achieving a $5 actual CPA. The campaign can continue finding efficient conversion opportunities while its budget limits available spending. Google will change this behaviour starting August 17, 2026.

After the change, affected campaigns will optimise more closely toward the target entered by the advertiser. This means the system will focus more directly on the stated CPA or ROAS target. Advertisers who currently enjoy stronger performance could therefore notice different results after implementation. A campaign with a lower actual CPA could move closer toward its higher Target CPA.

Similarly, a campaign with stronger ROAS could move closer toward its stated Target ROAS. Google says this approach should make performance more predictable when advertisers increase campaign budgets. However, advertisers need to understand their current performance before making target changes. A target should reflect the results and business expectations that matter to the campaign.

Why Target CPA Matters

Target CPA tells Google’s bidding system how much an advertiser wants to spend per conversion. Advertisers often use this strategy when they want Google to pursue conversions around a specific acquisition cost. The August change can affect campaigns that currently achieve lower CPA than their stated target.

Consider a campaign with a $10 Target CPA and a $5 actual CPA. That campaign currently performs twice as efficiently as the stated target. After August 17, Google will optimize more closely toward the $10 target. The advertiser may therefore see actual CPA move closer to the stated target.

Advertisers who want to preserve their recent $5 CPA should review their target before August 17. The Bid Target Adjustment Tool can help them identify affected campaigns and review recent performance. Advertisers can then decide whether their current target still reflects their preferred performance level.

Why Target ROAS Matters

Target ROAS works around a desired return from advertising spend. Google will also apply the August 17 bidding change to affected campaigns using Target ROAS. A campaign might currently achieve a 6x ROAS while carrying a 3x target. That campaign significantly outperforms the target entered into Google Ads.

The new bidding behaviour will move optimisation closer toward the stated 3x ROAS target. Advertisers should therefore review campaigns that consistently exceed their existing ROAS targets. The same principle applies across Target CPA and Target ROAS strategies.

Your current target should represent the performance level you actually want from your campaign. Avoid assuming that a higher CPA target or lower ROAS target always produces better growth. The upcoming change makes accurate target setting more important for affected campaigns.

Which Google Ads Campaigns Does This Affect

The August 17 change covers several campaign types that use Target CPA or Target ROAS. These include Search campaigns, Shopping campaigns, Performance Max campaigns, Demand Gen campaigns, and Travel campaigns. Google does not apply this change to every campaign type.

App Campaigns, Video Reach campaigns, and Video View campaigns remain outside this specific change. Display and Hotel campaigns already use the newer bidding behaviour. Advertisers should therefore identify their campaign types before deciding whether this update affects them.

Performance Max campaigns deserve particular attention because they can experience additional traffic distribution changes. The algorithm may distribute traffic differently as it focuses more closely on the stated target. Advertisers should consider this possibility when reviewing Performance Max performance after the change.

How Budget Limited Campaigns Fit Into the Change

Budget status plays an important role in this Google Ads bidding update. The campaigns most likely to experience the change carry a Limited by budget status. These campaigns also use Target CPA or Target ROAS bidding. Google specifically targets campaigns where budget limits currently restrict spending opportunities.

Campaigns without budget constraints do not face the same direct impact from this update. Advertisers should therefore avoid changing every bidding target without checking campaign status first. Start by identifying campaigns that currently show Limited by budget.

Then check whether those campaigns use Target CPA or Target ROAS. Finally, compare the stated target against recent actual performance. This process helps advertisers identify the campaigns that deserve closer attention before August 17.

What the Bid Target Adjustment Tool Does

Google introduced the Bid Target Adjustment Tool for this transition. The tool became available inside Google Ads on July 6, 2026. It helps advertisers identify campaigns affected by the upcoming bidding change. The tool also provides historical actual performance for each affected campaign. Advertisers can review those results before deciding whether to change their targets. The tool supports individual target updates as well as bulk updates.

This feature gives advertisers a practical way to review several affected campaigns together. Advertisers who want to maintain recent performance can align targets with actual recent results. Advertisers who accept movement toward their existing targets may choose not to change anything.

The tool does not automatically change bidding targets for advertisers. Google also does not automatically change campaign budgets because of this update. Advertisers must make target changes themselves when they want different bidding behaviour.

How to Review Your Google Ads Campaigns

Start your review by checking every campaign that uses Target CPA or Target ROAS. Next, identify campaigns that currently show a Limited by budget status. After that, compare each campaign’s target against its recent actual performance.

A 30 day performance comparison can provide a useful reference for this review. For Target CPA campaigns, compare your stated CPA with your actual CPA. For Target ROAS campaigns, compare your stated ROAS with your actual ROAS. Utilizing professional marketing analytics services allows you to track these trends accurately and evaluate post-update performance.

These campaigns could experience the most noticeable changes after August 17. Document the current target, actual performance, and any target changes you make. This record will help you compare campaign performance after Google’s new bidding behaviour takes effect.

What Advertisers Should Review Before August 17

The deadline creates a useful opportunity to audit existing bidding targets. Many advertisers set targets earlier and never update them as campaigns develop. Performance can change over time as campaigns collect more conversion data. A target that once made sense may no longer match recent campaign performance.

The August 17 change gives advertisers a clear reason to review those settings. Start with budget limited campaigns because they receive the direct focus of this update. Then review actual CPA or ROAS against the target entered into Google Ads. Identify campaigns where actual performance consistently exceeds the stated target.

Decide whether the current target still represents your preferred performance level. Update targets when your recent results support a different target. Document every change so you can evaluate performance after August 17. This approach keeps bidding decisions connected to actual campaign data rather than assumptions.

What Happens If You Do Nothing

Google will not automatically change your bidding targets on August 17. The system will instead change how affected campaigns optimise toward their existing targets. If your campaign already matches its intended target, you may choose to leave it unchanged.

If your campaign significantly outperforms its target, review that target before the deadline. Advertisers who want to maintain recent performance should consider updating targets beforehand. The decision depends on the target you actually want the campaign to pursue.

You should not change targets simply because Google announced the bidding update. Review the numbers first and make decisions based on your recent campaign performance. This approach helps prevent unnecessary changes across campaigns that do not require adjustment.

What Performance Max Advertisers Should Know

Performance Max campaigns using Target CPA or Target ROAS can fall within the affected group. The campaign must also carry a Limited by budget status for the specific change. Advertisers should therefore check both the bidding strategy and budget status.

Performance Max campaigns may also experience changes in traffic distribution across available channels. Google’s system will focus more closely on the stated target under the new bidding behaviour. This could influence how the campaign finds and distributes traffic opportunities.

Advertisers should document current performance before making any target adjustments. That baseline can help them understand changes after August 17. The same review process applies to other affected target based campaigns.

A Simple Preparation Checklist

You can prepare for the Google Ads bidding update with a focused review.

 

1. First, find campaigns that currently show Limited by budget. 
2. Next, identify campaigns that use Target CPA or Target ROAS.
3.  Then compare each target with actual performance from the recent 30 day period.
4. Look for campaigns where actual results significantly outperform the stated target. 
5. Review those targets and decide whether they still match your campaign objectives.
6. Use Google’s Bid Target Adjustment Tool when you need help reviewing affected campaigns.
7. Update targets individually or in bulk when your review supports those changes.
8. Record your changes before August 17.
9.  Finally, compare future performance against your documented pre update results.

This process gives you a clear reference point for evaluating campaign changes.

 

Frequently Asked Questions

 

• 1. Will Google automatically change my Target CPA or Target ROAS?

No, Google will not automatically change your existing bidding targets. The update changes how affected campaigns optimize toward the targets already entered. Advertisers must manually change targets when they want different target values. Google provides the Bid Target Adjustment Tool to support this review process.

 

• 2. Does every Google Ads campaign face this bidding change?

No, the update only affects specific campaign types using target based bidding. Search, Shopping, Performance Max, Demand Gen, and Travel campaigns can fall within scope. App Campaigns, Video Reach, and Video View campaigns remain outside this change. Display and Hotel campaigns already follow the newer bidding behaviour.

 

• 3. What if my campaign does not show Limited by budget?

Campaigns without budget constraints do not face the direct impact of this update. Google specifically focuses this change on budget limited target based campaigns. You should still review your account to confirm each campaign’s current status. Avoid making target changes without checking the actual campaign conditions first.

 

• 4. When should advertisers review their bidding targets?

Google recommends completing target reviews before August 17, 2026. Reviewing campaigns earlier gives advertisers more time to assess their settings. It also gives campaigns more time to respond to target adjustments before implementation. Waiting until the deadline leaves less room for careful review and comparison.

Conclusion

Google’s August 17 bidding change introduces an important adjustment for affected target based campaigns. The biggest concern involves budget limited campaigns using Target CPA or Target ROAS. These campaigns may optimise more closely toward the targets advertisers have entered.

Advertisers who currently outperform their targets should review their settings before August 17. Google’s Bid Target Adjustment Tool provides a practical way to identify affected campaigns. The tool also helps advertisers review recent performance and update targets when necessary. A careful campaign audit can help advertisers understand where this update may create changes.

Start with budget status, bidding strategy, actual performance, and current targets. Then decide whether your existing targets still represent the results you want. The goal does not involve changing every campaign before August 17. The goal involves understanding which campaigns face the change and making informed bidding decisions.

A focused review can help you enter the August 17 update with clearer expectations. More importantly, it can keep your Google Ads targets aligned with your actual campaign performance. For ongoing account auditing and growth, specialized performance marketing optimization can safeguard your conversion targets and ROI across all active campaigns.
