Google has started rolling out its September 2026 spam update, the fourth spam update of the year. The update went live on September 24 at 9:15 a.m. PDT, according to the Google Search Status Dashboard, and it applies globally and to all languages.
Google’s status update says:
“Released the September 2026 spam update, which applies globally and to all languages. The rollout may take up to two weeks to complete.”
Google has not shared additional details on which spam policies or tactics this update targets.
How this update compares
September’s rollout follows spam updates in March, June, and August. Earlier updates wrapped up much faster than the current estimate:
- March 2026: 19 hours, 30 minutes
- June 2026: 2 days, 1 hour
- August 2026: 2 days, 16 hours
Previous spam updates carried an expected rollout window of “a few days.” For September, Google says the process may take up to two weeks. That does not mean the full window will be used, but it signals a potentially longer period of ranking volatility.
What SEOs should watch
Spam updates improve Google’s automated systems for detecting search spam. When visibility shifts during a rollout, timing matters. If you see a drop, first check Google Search Console data and compare the change to the update’s start date.
Google’s guidance is direct: sites that see changes after a spam update should review its spam policies. Pages that violate those policies may rank lower or not appear in results at all.
Recovery is not instant. If you fix issues, Google says automated systems can learn over a period of months that a site is complying with spam policies.
Use the rollout as an audit trigger
Even if your site appears stable, use the two-week window to audit for scaled or low-value content. A simple triage can help:
- Stable pages: no immediate action; watch for delayed fluctuations.
- Volatile pages: inspect for indexing changes, recent edits, or spam signals.
- Declining pages: compare Search Console clicks and impressions with the early rollout dates.
Not every ranking dip is spam-related. Algorithm rollouts, seasonality, tracking gaps, and core changes can all move traffic. But if declines cluster around pages that push content boundaries, treat the update as a signal to clean up before Google’s systems make a longer-term judgment.
