Google’s August 2026 spam update rolled out from August 18 through August 21, accompanied by unconfirmed ranking volatility before and after the spam push. During the same period, Google began routing searchers from AI Overviews into AI Mode, introduced link carousel cards for developing stories, and started powering parts of AI Mode with Gemini 3.7 Flash. New google.com/goto URL parameters appeared in search results, and Search Console’s generative AI performance reports expanded to more properties.
What changed in Google Search ranking and spam enforcement
The headline ranking event was the Google August 2026 spam update, which started rolling out on August 18 and completed on August 21. Unconfirmed ranking volatility also spiked around August 5 to 6, August 12 to 13, and again after the spam update finished, leaving several days of noticeable movement in the search results.
Separately, Google confirmed that it will not enforce manual actions for its site reputation abuse policy against sites whose results are shown to searchers in the EEA. Google’s explanation framed the policy change as a legal requirement rather than a ranking change.
On the topic of transparency, Google clarified why it announces some search updates but not others, saying that only updates with actionable content for site owners get blog posts, and that the company does not intentionally time rollouts to coincide with announcements.
How AI Mode is expanding inside Google Search
Google began pushing searchers from AI Overviews directly into AI Mode, including dropping the “show more” button inside the overview surface. Once inside AI Mode, users now see link carousel cards designed for developing stories. Google also tested AI-generated images inside AI Overviews before pausing the test shortly after launch.
On the model side, Google confirmed that AI Mode is partially powered by Gemini 3.7 Flash. Other AI Mode additions reported during the month include flight price tracking, airline mile rates, hotel booking, and a prompt to sign in. AI Overviews gained copyable emojis, began appearing above stock charts for stock price queries, and were observed pulling local results from low-quality listicles.
New google.com/goto parameters, home page buttons, and source controls
Google Search started rolling out new google.com/goto URL parameters on result links. The framing from Google is that the change helps protect its results from third-party scraping tools, and the source noted that scraping tools already have fixes ready for the shift.
The Google home page gained test buttons for “Create Images,” “Ask About Files,” and “Brainstorm,” signaling a more assistant-oriented entry point. The Preferred Source button for publishers was improved, and Google lowered the subscriber requirement for Search Profiles. Search Profiles also now let users edit their handle.
Other search-feature changes reported in the recap: the video carousel is showing less often, Google tested pink highlights inside featured snippets, and the Discover feed can be tailored by keywords.
Google SEO clarifications, crawling notes, and content visibility
Google addressed several recurring SEO questions during the month:
- Reddit gets no special preference in Google Search rankings.
- There is nothing special for site owners to do to optimize for generative AI responses in Search.
- Google Search now lists the supported favicon file formats, after Google fixed a bug with favicons and crawl stats that caused complaints about disappearing favicons.
- Search temporarily showed fewer PDF files in results, and the IRS website dropped heavily in Google before recovering.
- Hreflang URLs are not indexed in the traditional sense, and JSON-LD extraction for Googlebot now does one pass of HTML unescaping.
- Google says its crawlers send HTTP requests including HEAD, OPTIONS, PUT, PATCH, and DELETE, but do not parse JSON.
- Misconfiguring Cloudflare can hurt SEO, and Googlebot may report being from California while actually being located elsewhere.
Google Search Console updates and bugs
The generative AI performance report in Search Console expanded to more properties. Search Console can now show AI Mode queries, though those queries do not yet appear inside the dedicated generative AI reports. Performance reports showed a drop in impressions and clicks around August 12.
Crawl Stats missed two days of data, which Google attributed to a fix for a favicon and crawl stats bug. Search Console also sent new owner email notifications that some site owners flagged as a possible bug, and the selected canonical signal was observed showing spammy values on some sites.
Google Business Profile and local changes
Google acknowledged a problem with reviews missing after Google Business Profile reinstatement. Google also began bringing back Google Posts insights, specifically the “people viewed” metric, and started testing a revamped Q&A feature inside Business Profiles. On the policy side, Google Local now disallows repeated bilingual name transliterations.
Industry and business moves around Google Search
Google made notable AI leadership changes during the month, with Jeff Dean leaving and Demis Hassabis taking on a changed role. Google also amended its lawsuit against SerpApi over licensed content. Separately, SEOs have been taking over expired Google X accounts.
One ecosystem change worth noting: Google Assistant is shutting down on mobile devices on September 4.
