Google September 2026 Spam Update Finished After Nearly 14 Days

Key Takeaways

• Google's September 2026 spam update began on September 24, 2026 and was marked complete on October 8, 2026 — nearly 14 days, according to the Google Search Status Dashboard.
• It applied globally and to all languages.
• It was Google's fourth spam update of 2026, after March, June and August. The earlier 2026 spam updates each finished in a few days; this one ran about two weeks.
• Google did not publish a list of the specific techniques it targeted. A spam update enforces Google's spam policies; it is not a core update about general content quality.

What Happened

Google announced the update on the Search Status Dashboard on September 24, 2026, at around 9:15 a.m. PT, and marked it complete on October 8, 2026. Search Engine Land and Search Engine Roundtable reported both the start and the completion; Search Engine Journal described the rollout as nearly 14 days.

For context, the August 2026 spam update ran from August 18 to August 21. The full 2026 timeline is in our Google algorithm updates tracker.

Spam update or manual action?

The two are different, and they are checked in different places:

• A spam update is algorithmic. If a site lost visibility during September 24 – October 8, Search Console shows no message; you see it as a drop in impressions and clicks.
• A manual action is a human review. It appears in Search Console under Security & Manual Actions › Manual actions, names the issue, and needs a fix followed by a reconsideration request.

Google has not said that this update was connected to manual actions, so treat any drop you see as algorithmic unless Search Console shows a manual action.

What to check if your traffic moved

1. Compare the dates. In the Search Console Performance report, compare the weeks before September 24 with the weeks after October 8. A change that starts inside the rollout window is worth investigating; a change before or after it probably has another cause.
2. Look at which pages dropped. Group the affected URLs by template or directory. Spam updates tend to hit patterns — mass-produced pages, doorway pages, or content hosted for a third party — rather than one page at random.
3. Read the spam policies against those pages. Google's spam policies list what is covered, including scaled content abuse, site reputation abuse and expired domain abuse. Fix or remove the pages that match, rather than rewriting the whole site.
4. Check Manual actions anyway. It takes a minute, and it tells you whether a human reviewer is involved.
5. Expect recovery to take time. Google says changes are picked up as it recrawls and reprocesses pages; there is no fixed recovery date.
