September 2026 Google Webmaster Report: Spam Update, AI Mode Push, and GoTo Redirects

A monthly recap of Google SEO news: the August 2026 spam update, AI Mode expansion, new goto URL parameters, and Search Console changes.

Google closed August 2026 with a completed spam update and rolled straight into September with sweeping AI Mode changes, new tracking parameters for search result URLs, and several Search Console fixes. The biggest stories of the month include the four-day spam update, a policy carve-out for the EEA, and a steady push of AI Mode into AI Overviews, plus a leadership shake-up inside Google’s AI unit.

Here is what site owners, SEOs, and publishers need to know from the past month of Google search news.

What happened with the Google August 2026 spam update?

Google launched the August 2026 spam update on August 18 and finished rolling it out on August 21, a four-day event that targeted spammy content signals across Search. Volatility in rankings was reported both before and after the official window, including noticeable movement around August 5 to 6 and again on August 12 to 13.

Google also explained why it announces some search updates and not others, stating that it publishes posts only for transparent, actionable updates that site owners can respond to.

How is Google changing its site reputation abuse policy in Europe?

Google updated its site reputation abuse policy so manual actions tied to the policy will not be enforced against sites that primarily serve searchers in the EEA. The carve-out applies to site reputation enforcement specifically; it does not lift other spam policies. Google framed the change as a legal compliance move rather than a global policy shift.

What is changing inside Google AI Overviews and AI Mode?

Google is pushing AI Mode into AI Overviews inside Google Search, dropping the Show More button on many results and routing users into a richer AI-driven experience. AI Mode can now display link carousel cards for developing stories, and a test briefly placed AI-generated images inside AI Overviews before Google paused the test.

Under the hood, Google confirmed AI Mode is partially powered by Gemini 3.7 Flash. New AI Mode features include flight price tracking, mileage-based hotel booking, sign-in prompts, and AI Overview local results that pull from low-quality listicles. Google also began showing AI Overviews above stock charts for stock-price queries and added copyable emojis to AI Overview answers.

Why is Google adding google.com/goto URL parameters?

Google started rolling out new google.com/goto tracking parameters on its search result URLs, a change the company says is meant to protect search results from third-party scraping tools. The move is widely seen as aimed at SerpAPI, which Google is currently fighting in court over licensed content. Third-party SEO tools have already shipped fixes to keep their tracking intact.

What changed on the Google home page and in publisher tools?

Google tested new buttons on its home page labeled Create Images, Ask About Files, and Brainstorm, signaling deeper AI integration at the entry point of Search. Google also improved the Preferred Source feature for publishers and lowered the subscriber requirement needed to appear in Search profiles. Users can now edit their handle on Google Search profiles.

Other interface tweaks: the Search video carousel is showing less often, Google tested pink highlights inside featured snippets, and the Discover feed can now be tailored by user-selected words. Google Assistant on mobile devices is scheduled to shut down on September 4.

What Google said about Reddit, generative AI responses, and PDFs

Google clarified that Reddit receives no special preference in Google Search rankings. Google also said there is nothing special that publishers need to do to appear in generative AI responses in Search, and Search Console will not surface a separate optimization checklist for AI answers.

Google temporarily showed fewer PDFs in search results, and the IRS website dropped heavily in Google visibility during the period before recovering. Google’s crawlers were observed sending HEAD, OPTIONS, PUT, PATCH, and DELETE HTTP requests. Google also clarified that JSON-LD extraction for Googlebot now does one pass of HTML unescaping, that hreflang URLs are not indexed in the traditional sense, and that Google’s crawlers do not parse JSON. Misconfiguring Cloudflare can hurt SEO, and Googlebot may report a California origin while running from elsewhere.

What changed inside Google Search Console?

The Search Console Generative AI performance report expanded to more sites, while a separate view now surfaces AI Mode queries that do not yet appear in the Generative AI reports. A drop in impressions and clicks around August 12 showed up in Performance reports, and Crawl Stats went missing for two days of data. Google also began sending new owner email notifications, though the flow had a reported bug, and Search Console surfaced a spammy Selected Canonical entry that webmasters flagged.

What is new for Google Business Profiles and local search?

Google acknowledged that reviews can go missing after a Google Business Profile reinstatement and is investigating the issue. Google is also bringing back Google Posts insights, showing a People Viewed count, and is testing a revamped Q&A feature inside Business Profiles. On the policy side, Google Local now disallows repeated bilingual names and transliterations on a listing.

What AI leadership changes happened at Google?

Google announced internal AI leadership changes in late August. Jeff Dean is leaving his role, and Demis Hassabis’s responsibilities are shifting as part of a broader reorganization of Google’s AI teams.

What is the latest in the Google versus SerpAPI lawsuit?

Google amended its lawsuit against SerpAPI over licensed content, escalating an ongoing dispute about how third-party tools access Google Search results. The new google.com/goto URL rollout sits alongside that legal fight and is widely read as a related defensive measure.
