It has been a rough first week of September 2026 for Google's advertising infrastructure. First a Google Analytics 4 reporting bug wiped out visible traffic data on September 1. Now a second, unrelated bug is unlinking Local Service Ads accounts from their Google Business Profiles across every market where the product runs, and Google has confirmed it directly.

Wherever your AdSense account is registered, the same change lands on the same day: February 17, 2027. Google is switching the entire platform from "count-on-download" to "begin-to-render" measurement, and every publisher running display, mobile web, or CTV banner inventory will see the effect in their dashboard the same week, regardless of country, currency, or ad network setup.

Google has spent the past few weeks quietly rewriting how it measures advertising performance across its own ecosystem. AdSense announced a switch to begin-to-render impression counting starting February 2027. Now, as of August 24, 2026, Merchant Center has overhauled its own reporting - and unlike the AdSense change, this one reaches backward, rewriting historical data all the way back to July 1, 2026, months before the change itself was even made publicly known to sellers anywhere.

On August 13, 2026, a recipe publisher documented that Google's AI Overviews had generated a cartoon-style illustration for a spaghetti squash query - with no image request, no AI-generated label, and no source attribution. On August 17, Google VP of Product Robby Stein confirmed to Search Engine Land: "This was a small experiment we're no longer running."

The platform properties feature gave Instagram, TikTok, YouTube and X account owners something that simply did not exist before: direct visibility into how their content shows up in Google itself, not just inside the platform's own analytics. We covered the launch of the feature in detail in our guide to the new Search Console reports. This piece is about what it looks like once you actually start using it day to day.
