Google Ads August 17 Bidding Target Change and June 2026 Policy and Tracking Updates

Question 1

What will happen to my budget-limited campaigns on August 17, 2026 if they beat their tCPA or tROAS target?

Accepted Answer

According to groas, Google confirmed on June 15 that starting August 17, 2026, any budget-limited campaign over-delivering its stated tCPA or tROAS target will be automatically pulled back toward that target, with no opt-out. The article states the campaigns most at risk are those quietly beating their goals, for example a $50 tCPA delivering at $35, because Google will enforce the ceiling rather than letting the algorithm spend aggressively. The article recommends auditing every budget-limited campaign now and updating targets that consistently trail actual performance before August 17.

Question 2

What is the July 6 Bid Target Adjustment Tool and what should I do before the August deadline?

Accepted Answer

The article reports that a Bid Target Adjustment Tool launches July 6 to surface historical performance data so advertisers can decide whether to revise targets before the behavioral change. Google has confirmed the change spans Search Ads 360, DV360, Google Ads Editor, and the Google Ads API. The article advises not waiting until August to act, even though waiting until the July 6 tool launch is acceptable.

Question 3

How does the Limited Ad Serving policy expansion to Google Search affect my impressions?

Accepted Answer

The article states Google extended its Limited Ad Serving policy to Google Search on June 12, 2026, giving Google authority to cap ad frequency for advertisers it deems “unqualified,” even if fully policy-compliant. A key trigger is persistent, disproportionate user complaints, including off-platform reputation, review-site patterns, and consumer protection filings. The policy previously covered YouTube since September 2024, the Search expansion is gradual and will be fully implemented by 2028, but the mechanism is already live for some accounts.

Question 4

What can I now A/B test in Performance Max asset experiments?

Accepted Answer

According to the article, Google began the global rollout of structured asset experiments for Performance Max on June 8, 2026. Advertisers can now A/B test entire asset groups, individual assets, or seasonal versus evergreen creative, including AI-generated assets from Google’s Asset Studio, and can evaluate experiments against two success metrics simultaneously such as ROAS and conversion volume. Experiment types including conversion lift studies are being consolidated under one Experiments page, with MCC and API support coming in the weeks ahead.

Question 5

Why did my offline conversion imports stop working after June 15, 2026?

Accepted Answer

The article reports that as of June 15, 2026, the Google Ads API’s UploadClickConversions endpoint no longer accepts new adopters of offline conversion imports or enhanced conversions for leads, and developer tokens without active usage between January and June 2026 now return hard errors. All new offline conversion workflows must use the Data Manager API. The article warns the failure is silent with no UI error, causing Smart Bidding signals to degrade, CPA to creep up, and volume to drop.

Question 6

What changed with GA4 Google Signals and Consent Mode on June 15, 2026?

Accepted Answer

The article states that also effective June 15, Google removed the ability for GA4’s Google Signals toggle to override what advertising data flows to Google Ads, making Consent Mode the sole gatekeeper. If consent banner code denies ad_storage, the account is restricted to anonymous URL-parameter-level data with no GA4 dashboard fallback. The article recommends checking consent banner setup and confirming ad_storage is granted when users accept cookies, because the change can quietly sever GA4 audience signals to Google Ads.
