Spam Update Still Driving Movement
Google's September 2026 spam update is still the main weather system. Google says it began September 24 at 9:15 a.m. PDT, applies globally and to all languages, and may take up to two weeks to finish. Search Engine Land and Search Engine Journal both frame this as the fourth spam update of 2026, with a longer rollout than the March, June, and August spam updates.
Search Engine Roundtable reported a first impact wave around September 25-27, then a second hit around September 30 and October 1, with site owners reporting sharp drops and unstable Discover traffic. That lines up with today's partial volatility reading of 6.8/10, still moderate-high, with some providers flashing very hot while others are calmer. The last week looks less like a one-day storm and more like a stubborn windy pattern.
Google's Content Bar Gets Clearer
The other notable development from the last 24-48 hours came October 2, when Search Engine Land and Search Engine Journal covered Google's updated helpful content guidance. Google now puts more weight, at least in its public wording, on main content, meaning the actual stuff that helps the page do its job: text, images, tools, reviews, tabs, headings, and other useful page elements.
Google's documentation also warns against fake author profiles, including AI headshots, made-up names, or false credentials. Separately, Google's AI content guidance now tells publishers to manually fact-check AI-generated content before publishing, including metadata like titles, descriptions, structured data, and image alt text.
Bottom Line
Do not panic-edit every page mid-rollout. Watch Search Console by page and query group, flag drops that began after September 24, and audit anything thin, templated, AI-scaled, or dressed up with fake expertise. If the page would not satisfy a real visitor, it is standing outside in the wind.
