This page answers the questions covered by the article Today In Google Ads: June 11, 2026 - Performance Max Gets Structured Asset A/B Testing (Rolling Out... on groas.com. The article is the full, canonical source.
Direct answer: According to the article, Google is rolling out structured asset A/B testing for Performance Max as of June 11, 2026, alongside a June 10 sunset of Ads API v20, June 15 deadlines for Consent Mode and phone call attribution, a 37-month granular data retention cap in effect since June 1, and an automatic DSA-to-AI Max upgrade starting in September 2026. The article recommends planning a first PMax experiment now, migrating API integrations immediately, auditing consent and call tracking before June 15, archiving data older than 37 months, and migrating from DSA voluntarily before September.
According to the article, Google is releasing asset experiments for Performance Max that let advertisers compare entire asset groups against each other, isolate the impact of adding individual assets, or run seasonal creative against evergreen variants, including assets generated through Google's Asset Studio. Conversion lift studies and standard experiments are being consolidated under a single Experiments page in the Google Ads UI, with MCC-level support and API access expected in the coming weeks. The article recommends planning a first experiment now while the rollout is still fresh.

According to the article, Google Ads API v20 officially ended June 10, 2026, and all v20 requests now return hard errors with no grace period. Teams running custom scripts, automated bidding pipelines, or integrations still calling v20 endpoints are broken and must migrate to a currently supported API version immediately. The article states this is especially urgent for agencies managing multiple accounts at scale, where a single outdated integration can cascade across an entire MCC.

Starting June 15, Google is restructuring how data flows between GA4 and Google Ads so the ad_storage parameter in Consent Mode becomes the single gate controlling all ad data collection for linked Ads accounts, eliminating the previous dual-gate system where Google Signals inside GA4 could override Ads-side behavior. According to the article, misconfigured consent banners will now cause silent losses to reporting accuracy, remarketing audience populations, and ROAS measurement without any dashboard warning. The article recommends auditing the Consent Mode implementation and verifying that ad_storage fires correctly across all consent scenarios if it has not been audited in the last 30 days.

According to the article, the same June 15 date brings a change to phone call attribution, and advertisers without updated tracking setups will lose visibility into which keywords, ads, and campaigns are driving phone calls. The article notes that call-only ads can no longer be created as of February 2026 and will stop serving entirely by February 2027, and that later in 2026 IP addresses collected by the Google tag will be encrypted before flowing to linked Google Ads accounts. The article recommends verifying call tracking configuration before June 15, particularly for local service businesses, legal firms, and healthcare advertisers where phone calls represent a significant share of conversion volume.

According to the article, effective June 1, 2026, Google Ads enforces a 37-month retention limit on granular reporting data covering hourly, daily, and weekly breakdowns, reversing the prior 11-year policy and affecting the Google Ads API, scripts, and BigQuery pipelines, while reach and frequency metrics carry an even shorter three-year limit. The article warns that manually triggering a BigQuery backfill for dates older than 37 months can actively overwrite and destroy existing historical data in tables. The article recommends exporting and archiving anything older than 37 months now rather than assuming existing BigQuery tables are safe.

According to the article, Google confirmed that Dynamic Search Ads, automatically created assets, and campaign-level broad match settings will all be automatically upgraded to AI Max for Search starting in September 2026, with new DSA creation ending at the same time. Google's published claim is that the full AI Max feature suite delivers 7% more conversions at similar CPA or ROAS, while independent research across 250+ retail campaigns showed 35% lower ROAS compared to traditional match types. The article recommends migrating voluntarily now to control the transition, preserve campaign settings, and establish a performance baseline before the forced migration.
