Google's September 2026 spam update delivered its first measurable ranking volatility over the weekend, then rolled out a second wave on Wednesday, September 30 and Thursday, October 1, according to the latest search news recap. The two-phase rollout drove the busiest week of webmaster chatter in months.

How much is Google paying publishers in the AI contribution pilot?

A report tracked this week put the figure at roughly 100 participating publishers, each receiving payouts equal to about 0.1% of their own ad revenue. Google has not publicly itemized the deals. The 0.1% figure — scaled on top of a publisher's existing ad stack — frames the program as closer to a goodwill credit than a true revenue line.

What changes hit AI Overviews and AI Mode this week?

Google returned AI Overviews for many large brand-name queries and team-roster searches, after months of suppression on those terms. A separate test moved the AI Overview citations block from the right rail to the bottom of the panel. Another experiment replaced the "Show more" button with a "Loading..." indicator.

On the AI Mode side, Google globally rolled out monitoring capabilities, letting users set ongoing queries that AI Mode will refresh in the background. Brand queries and sports rosters are the verticals most likely to see the visual shifts first, since those categories just returned to the AI Overview surface.

What did Google's Nick Fox say about European searchers?

Fox, a senior Google search executive, told a public forum that he "feels sad and terrible" for European users whose results are degraded by the EU's Digital Markets Act. Google separately filed an appeal against the DMA mandate to share search history data with rivals. The appeal puts the company on a parallel legal track in Brussels while it adjusts surface-level results for EEA traffic.

Which AI Overview lawsuit stalled?

A federal judge dismissed the Penske lawsuit against Google's AI Overviews, citing the absence of any underlying agreement between the publisher and Google. The dismissal lands as several publisher-side AI suits continue through U.S. courts, and as Google tests new citation card layouts on the very surface at issue.

What shipped on Google Maps and Business Profiles?

Google Maps now requires users to sign in to read all reviews, alongside a separate bug that placed some business pins in the middle of the ocean. Google Business Profiles added a new policy targeting misuse of support channels.

Local Service Ads surfaced two bugs: one serving ads in locations advertisers don't cover, and another hiding phone numbers by default before later revealing them in the funnel.

What did Microsoft, Bing, and OpenAI change?

Microsoft Advertising made optimization experiments generally available worldwide, letting advertisers A/B test campaign tweaks without whitelisting. Bing began testing a sponsored ad unit that appends a one-line consumer review next to the headline.

OpenAI pushed bulk product creation, product review status, and additional updates to ChatGPT Ads.

What UI tests is Google running?

A sponsored products grid that visually mirrors the organic product grid is now in rotation, raising fresh questions about disclosure on commercial queries. Google also tested removing the "I'm Feeling Lucky" button from the search bar. The company celebrated its 28th birthday with a doodle that routes users into an AI Mode quiz.

The week ahead turns on whether the September 2026 spam update produces a third wave, how EU regulators respond to Google's DMA appeal, and whether the bottom-positioned AI Overview citations card graduates from test to default.
