Google marked its September 2026 spam update complete on 8 October. The Google Search Status Dashboard logged the finish at 01:37 Pacific with a single line: “The rollout was complete as of October 8, 2026.”
The opening entry is dated 24 September at 09:15 Pacific. It says Google released the update, which “applies globally and to all languages,” and that the rollout “may take up to two weeks to complete.” The dashboard’s history page lists the run at 13 days and 16 hours.
Why it matters
That is the longest spam update on the dashboard’s 2026 list. The March 2026 spam update ran 19 hours and 30 minutes. June ran 2 days and 1 hour, and August ran 2 days and 16 hours. Only the February Discover update, a different kind of change at 21 days and 17 hours, ran longer in 2026.
Neither dashboard entry names a spam policy or says what the update targeted. Google gives a start, an end and the scope as global and all languages. Anything beyond that, including which sites lost visibility, has to come from your own data.
What to do with the window
The insight for marketing teams is the date range. A rollout that spans two weeks blurs the usual before-and-after comparison, because traffic moves while the update is still being applied. Pull Search Console data for 24 September to 8 October and compare it with the two weeks before the start and the two weeks after the finish. If organic landing pages dropped inside the window and stayed down afterwards, review them against Google’s spam guidance before you change anything else on the page.
Google has been tightening its written guidance in parallel. We covered its advice to factcheck AI content and metadata and its description of fabricated author profiles as deception. Those pages and this update sit in the same quarter, and a content audit can cover all three at once.
