Google's September 2026 spam update has finished rolling out

Google's search status dashboard shows the September 2026 spam update finished rolling out on October 8. It started strongly in September, and Search Engine Roundtable reported a final phase around October 4-6 that caused fresh ranking swings. Google did not detail which spam types it targeted.

Reports are mixed. One forum participant managing many Search Console accounts said most sites gained traffic; others reported losses. Experts warn that early numbers mislead because rankings keep settling after a rollout. A brief indexing report bug and a delayed performance report made the data harder to read.

A spam update improves Google's automated spam detection and demotes pages that break its rules, such as scaled low-value content, bought links and site reputation abuse. A core update instead reassesses which pages are most helpful overall.

Mass-produced AI pages with nothing new, bought links and rented domain authority are hit hardest. Small business sites with original, current content are usually not targeted and may gain as competitors drop.

Give it two to three weeks before judging the impact. Another core update is expected toward year end.

Search Console is the most reliable check. Compare the four weeks before and after the rollout in the performance report to see which pages and queries lost clicks. Losses concentrated on a few pages point to their content; an even, site-wide drop points to links or a sitewide practice. Manual actions are reported separately under Security and Manual Actions.

If your traffic moved, match the drop date to the rollout phases in Search Console, merge or remove near-duplicate pages that only swap a city or keyword, review your link history for bought or irrelevant links, and keep investing in pages that answer real customer questions.
