A year of Sistrix data on UK news, two sightings of AI Overviews changing shape, and a pair of Google Ads label updates all describe what searchers and advertisers can see, and each comes with a clear limit on what it measures.
Answer Layer Creep: AI Overviews Change Shape On The Page
Two sightings show Google adjusting how AI Overviews sit on the results page, one pushing web listings lower and one moving the source count beneath the answer. Google has not announced either change.
- AI Overviews for definition queries now open fully expanded Glenn Gabe flagged complete AI Overviews on definition searches with no Show more click, leaving web results below the fold. Google has not announced it, so glossary publishers should compare click-through rates before and after November 11.
- Google tests AI Overviews source count at the bottom of the answer Brodie Clark spotted a variant that puts the referenced-sites count beneath the response, with the full citation list appearing on hover. The reach of the test is unknown, and the click-loss concern is Barry Schwartz’s reading, not measured data.
Seen, Crawled, Indexed: Three Views Of What Google Surfaces
A year of Sistrix data, a Google warning about CDN migrations, and a John Mueller comment on indexing each touch how Google decides what to crawl, index, and show. Each carries a caveat about what it does not prove.
- UK News Sites Lose Google Visibility While Substack Doubles Press Gazette’s November 10 report, using Sistrix data, has BBC News falling from 41.8 to 20.35 while Substack rose from 13.48 to 27.94. Sistrix excludes Top Stories, AI Overviews, and Discover, and the result diversity explanation is one SEO consultant’s view, not a Google statement.
- Google Warns a New CDN Can Trigger a Crawl Surge at Your Origin Google’s Search Central blog says a CDN’s faster responses can lift Googlebot’s crawl rate while a cold cache sends every first request to the origin. It also warns that blanket bot rules and CAPTCHAs can lock crawlers out, and the post gives no figures on how large the surges run.
- Mueller: Unindexed Pages Point to a Quality Problem, Not Crawl Budget John Mueller said on Bluesky that persistent not indexed statuses usually reflect doubts about a site’s overall quality, and that shrinking a site does little to change that. Search Engine Roundtable noted the guidance is not new.
Labels Without Proof: Google Ads Changes What It Shows About Results
Two Google Ads updates change what advertisers can see about AI Max and Smart Bidding. Both alter a label or a matching route, and neither says anything about incremental results.
- New ValueTrack Tag Flags AI Max Clicks in Your Analytics The new {search_term_matchtype} parameter marks AI Max expansion traffic with an a value in landing page URLs, so teams can segment it in their own analytics. It reports the matching route only, so incremental lift stays unmeasured without a holdout or experiment.
- Google Ads Caps Smart Bidding Learning Label At Seven Days Google’s help page now limits the Learning status to seven days and no longer lists budget, target, creative, or targeting edits as triggers. The page does not promise stable performance after a change, and Google has published no measurement of how bidding behaves under the new rules.
Today’s Quick Hits
- Google Ads Tests a Customer Journey Card on the Overview Page The pilot card sorts users into Unaware, Aware, Consider, and Act for eligible Performance Max, Search, and Shopping accounts, and its figures are platform-reported with no independent validation.
- Google Ads Tests a Visit Site Link in Mobile Search Ad Text A screenshot from Sachin Patel shows a plain text Visit site anchor inside mobile ad descriptions, and Google has not said how far the test reaches.
- Google Spells Out Who Qualifies for Merchant Center Loyalty Add-On The updated help page sets three conditions for the add-on, and each Merchant Center account can select only one supported country, which forces a choice for multi-country merchants.
- Google Ads Brand Lists Only Recognize Global Canonical Brands Google says its brand library holds single global entries, so a regional variant stuck in review should be swapped for the main brand, and a brand exclusion cannot be limited to one country through the list alone.
- Google Ads Adds Audience Reach Setting That Warns Against Narrow Targeting The Limit audience reach control has three levels and Google’s own interface recommends leaving reach unrestricted, though Search Engine Land does not say whether it is a full rollout or a test.
