Google's helpful-content guide now spells out what counts as main content. On the engineering side, two All in One SEO advisories landed on October 2 — patch to 5.0.2.1, not 5.0.2.

A dated, source-checked look at what moved in search over the past day — split into an editorial track and an engineering track, with the unverified items flagged as such.

Google quietly extended its EEA aggregator and supplier units to local business queries on September 18. Here is what editors should brief and what engineers should ship.

Discover experiments with a summary layer between the feed and your article, Search profiles get badge documentation, and two new files land in Lighthouse audits.

Cloudflare lets sites refuse AI training without losing search. Google ships a Search profile badge that feeds Discover. Next.js corrects its bot caching guidance.

Google widened Search profile eligibility and published badge markup on September 16, while Schema.org shipped 30.1. Ranking systems stayed quiet.

September 5 was a slow day in search. Nothing is rolling out at Google, so we cover the standing AI Overviews behavior and a crawler documentation move worth a same-day robots.txt review.

AI Mode went quiet on citations. Google says that is a bug rather than a policy change, so hold off on rewriting anything around one week of referral data.

Google swapped the model behind AI Mode on September 2. No ranking update is running, so any citation shift this week traces to that swap.
