Google Ads has announced an important update to its target-based bid strategies that will affect advertisers running budget-limited campaigns. Beginning August 17, 2026, campaigns using Target CPA, Target ROAS, and certain Target CPC strategies will more consistently deliver performance closer to the targets advertisers set.
Google is also introducing a Bid Target Adjustment Tool to help advertisers review and update campaign settings before the rollout.
For businesses relying on Google Ads Management Services, this change could affect lead generation costs, return on ad spend (ROAS), and campaign performance if targets have not been reviewed recently.
What Is Changing in Google Ads?
Google is updating how Smart Bidding behaves for campaigns that are Limited by budget.
Previously, these campaigns could sometimes outperform their Target CPA or Target ROAS because the system optimized around budget constraints.
After the update:
- Campaigns will align more closely with the Target CPA or Target ROAS you set.
- Budget increases may no longer produce the same unexpected efficiency gains.
- Advertisers should review target values before August 17, 2026.
Which Campaign Types Are Affected?
The update applies to campaigns using target-based bidding, including:
- Google Search Campaigns
- Google Shopping Campaigns
- Performance Max Campaigns
- Demand Gen Campaigns
It primarily impacts:
- Target CPA
- Target ROAS
- Target CPC (Demand Gen only)
Why This Update Matters
Many advertisers intentionally set higher-efficiency targets years ago and never updated them.
Example:
- Target CPA: $20
- Actual CPA: $11
After the update, Google may gradually move campaign performance closer to the configured $20 Target CPA unless you update it.
