Your Target CPA has been lying to you, and starting August 17, Google will call the bluff.
Here's the scenario I've seen in dozens of pipeline reviews: a B2B marketing team sets a $150 Target CPA two years ago, the campaign quietly delivers leads at $95, and nobody touches the setting because the numbers look good. The budget stays capped, the leads keep flowing, and the target becomes a relic nobody remembers setting.
That quiet over-performance is about to end. Google announced on June 15 that budget-limited campaigns using Target CPA or Target ROAS will now be steered back toward the targets advertisers actually set. If your stated target is $150 and you've been getting $95, expect the algorithm to start spending closer to $150 per conversion.
This isn't a bug. It's Google enforcing the contract you forgot you signed.
The Math Your CFO Will Notice
Let me walk through what this looks like in a real forecast. Suppose you're running a mid-market SaaS campaign with a $10,000 monthly budget, a stated Target CPA of $150, and actual delivery at $95. You're getting roughly 105 conversions per month.
After August 17, if Google pulls performance toward your stated $150 target, that same $10,000 budget yields approximately 67 conversions. That's a 36% drop in lead volume with zero change to your budget or campaign structure.
Google's own documentation confirms it will not automatically adjust your targets or budgets. Advertiser action is required. Translation: if you don't fix this before August 17, you own the outcome.
The CFO question writes itself: why did we lose a third of our paid leads in Q3? The answer cannot be "we forgot to update a number in Google Ads."
The Six-Week Window
Google is shipping a Bid Target Adjustment Tool on July 6 that surfaces historical performance and gives you three options: keep the target, match it to recent performance, or set a custom target. You have six weeks between tool availability and the August 17 enforcement date.
This is not a drill. It's a forcing function for hygiene you should have been doing quarterly.
The tool will trigger account notifications for advertisers with budget-limited target-based campaigns in the past 12 months. If you're running Target CPA or Target ROAS on Search, Shopping, Display, Video, Demand Gen, or Performance Max campaigns, you're in scope. App campaigns, Hotel campaigns, and Local Services Ads are excluded from this change.
The Intention Gap
The real question isn't whether your targets are accurate. It's whether your over-performance was deliberate strategy or drift.
Some teams intentionally set conservative targets as a scaling lever. They know a $150 target with a $10,000 budget will force the algorithm to be selective, and they accept lower volume for higher quality. If that's you, and you want to maintain that behavior, you need to lower your target before August 17 to match your actual desired CPA.
Other teams simply never updated the target after performance improved. The landing page got better, the audience refined itself, the market shifted. The $150 target became a $95 reality, and nobody noticed because the dashboard showed green. If that's you, the fix is straightforward: update the target to reflect your actual acceptable cost.
As one analysis noted, a higher CPA can sometimes be acceptable if the leads are better, the job value is higher, or the business wants more volume. But it should be an intentional decision, not a setting inherited from last year's account structure.
The Audit Checklist
Between now and July 6, pull every budget-limited campaign running Target CPA or Target ROAS. For each one, document three numbers: the stated target, the actual 90-day average, and the gap between them.
Any campaign where actual performance beats stated target by more than 15% needs a decision. Not a review. A decision, documented in writing, with a rationale your CFO can read.
When the Bid Target Adjustment Tool arrives July 6, use it to validate your numbers against Google's view. If there's a discrepancy, trust your own data but investigate the delta.
By August 1, every target should reflect either your actual acceptable cost or a deliberate conservative buffer you can defend in a pipeline review. No orphan settings. No "we'll get to it next quarter."
Two Other Changes Worth Tracking
The June 15 announcement included two additional updates that matter for B2B marketers.
Smart Bidding Exploration is now available globally across all languages for Search and Performance Max campaigns without a product feed. The feature helps campaigns find additional converting traffic beyond queries they would normally pursue under existing bidding targets. For B2B accounts constrained by volume, this is worth testing, but run it as a controlled experiment with a holdout, not a blanket rollout.
Promotion Mode is entering beta for Search and Performance Max campaigns. It allows temporary budget flexibility and adjusted ROAS tolerance around specific events like product launches or end-of-quarter pushes. Google hasn't provided details about beta eligibility, but if you're regularly making manual bidding adjustments around promotional periods, this could simplify planning.
The Board-Ready Summary
Google is enforcing target discipline on budget-limited campaigns starting August 17, 2026. Campaigns that have been beating their stated Target CPA or Target ROAS will be pulled back toward those targets. The Bid Target Adjustment Tool arrives July 6, giving you six weeks to audit and update.
The risk is a material drop in lead volume with no corresponding budget change. The mitigation is a target audit completed before August 1.
If your paid search contributes more than 20% of pipeline, this belongs in your next forecast review. Model the impact, document your decisions, and update your targets with intent. The algorithm is about to do exactly what you told it to do. Make sure you meant it.
