Google Ads Updates June 16, 2026: Consent Mode, DSA to AI Max, and PMax Tests

Question 1

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

Accepted Answer

According to groas, as of June 15, 2026 Consent Mode treats ad_storage as the single, binary control for whether advertising data reaches Google Ads, removing the prior dual-gate where GA4 Google Signals settings could independently pass advertising data. If ad_storage is denied for a session, that session is invisible to Ads with no remarketing list inclusion, no conversion attribution, and no signal override from GA4. The article recommends auditing the consent implementation to confirm ad_storage is set correctly and reviewing remarketing audience sizes over the next 7 to 14 days for unexpected drops.

Question 2

When will Dynamic Search Ads be migrated to AI Max?

Accepted Answer

The article states the timeline is now a voluntary testing window from June 2026 through January 2027, an end to new DSA campaign creation in January 2027, and automatic migration of remaining DSA campaigns in February 2027. The destination has not changed and DSA is being replaced by AI Max. The article recommends using the voluntary window to run an AI Max campaign alongside DSA campaigns, compare performance on matched traffic segments, and document where AI Max under-delivers before the forced migration.

Question 3

Does limited ad serving now apply to Google Search?

Accepted Answer

According to groas, Google announced on June 12 that its limited ad serving policy now extends to Search results pages, with enforcement that began this month and will phase in fully through 2028. The article states the policy creates a qualification tier for newer or unverified advertisers that may restrict ability to serve ads on Search until enough trust history is built. For established accounts with clean histories near-term impact should be minimal, while advertisers launching new accounts or brands should factor in a ramp-up period where impression volume may be constrained.

Question 4

What new Performance Max A/B experiment types launched on June 8?

Accepted Answer

According to groas, the June 8 expansion added experiment types that let advertisers compare asset groups, test individual asset additions, and pit seasonal creative against evergreen content in structured A/B tests. The article states the capability originated as a retail-only beta in October 2024, broadened to all PMax campaign types in January 2026, and the June 8 update adds the new experiment types. Constraints remain at only one experiment per campaign at a time, and asset groups lock once a test starts.

Question 5

What happens if my account still uses Google Ads API v20?

Accepted Answer

According to groas, Google Ads API v20 stopped accepting requests on June 10, so bidding scripts, reporting pipelines, and campaign management workflows on an unsupported version are now operating with broken automation. The article states this already happened and unexplained data gaps or stalled bid adjustments point to an unsupported API version as the likely cause. The article recommends upgrading immediately to a supported version and backfilling data gaps from the downtime window.
