Google announced the September 2026 spam update on September 24, 2026. The rollout is expected to take up to two weeks. During a broad spam-system rollout, a technical SEO team should avoid treating every ranking movement as proof of a penalty and instead compare affected page groups, site changes, and known Search changes.
What the September 2026 spam update is
The update is a spam-system rollout that can affect how Google's systems identify and handle spammy content and practices. Google said the rollout began on September 24 and can take up to two weeks.
Do not react to one-day ranking changes
A rollout is not an instant before-and-after test. Rankings can move while systems are changing, so record the dates and compare several page groups instead of reacting to one keyword or one day's traffic.
What to check during the rollout
- Review pages with the largest organic traffic changes.
- Group affected URLs by template, topic, intent, and link pattern.
- Check for recent site changes that could explain the movement.
- Review manual actions and security issues in Search Console.
- Look for scaled, low-value, copied, or deceptive content patterns where relevant.
- Keep a dated log of changes and observations.
What not to do
Do not mass-delete pages or rewrite an entire site because of a short-term movement during the rollout. First identify whether the change is broad, limited to specific page groups, or linked to a known technical issue.
How to build a useful monitoring sheet
Track date, page group, clicks, impressions, average position, indexed status, major site changes, and notes about the rollout. Keep observed traffic changes separate from assumptions about why Google changed the results.
