Google has released its September 2026 spam update, and this one looks a little different from the three spam updates that came before it this year. Here’s what’s changed, what Google has said so far, and what I’d recommend doing (and not doing) while it rolls out.
September 2026 Spam Update — Quick Summary
- Started: September 24, 2026
- Scope: Global, all languages
- Rollout time: Up to 2 weeks
- Focus: Not officially confirmed
- Type: Spam update (longer rollout than usual)
What happened
Google started rolling out the September 2026 spam update on September 24 at 9:15 a.m. Pacific Time, according to Google’s Search Status Dashboard. The update applies globally, across all languages, and Google says it may take up to two weeks to complete.
This is the fourth spam update of 2026, following updates in March, June, and August, which makes 2026 the most active year for spam updates since 2021.
Why this rollout is different
Each of the earlier 2026 spam updates finished in a matter of days: March wrapped up in a day, June took a little over two days, and August took about two and a half. This time, Google has given itself a much longer window, up to two weeks, putting it closer to the timeline it usually reserves for core updates rather than spam updates.
That doesn’t necessarily mean the update itself is bigger. It does mean ranking changes may show up gradually over the coming two weeks rather than all at once, so it’s worth waiting out the full window before drawing conclusions from early movement.
What Google hasn’t said
As with previous spam updates, Google hasn’t named a specific spam tactic or policy this update targets, or estimated what percentage of searches will be affected. While some industry speculation points toward AI-generated spam and scaled content abuse, Google has not confirmed any specific focus for this update.
What to do if you see ranking changes
If you notice traffic or ranking shifts while this update is rolling out, don’t make sweeping changes based on a few days of data. Google’s own guidance is to review its spam policies and check whether anything on your site could fall under them, rather than reacting to short-term fluctuations.
A few practical steps:
- Check Search Console for manual actions or unusual drops tied to specific pages or sections.
- Review your site against Google’s spam policies, particularly around scaled content abuse, site reputation abuse, and expired domain abuse, since these have been recurring themes in 2026’s updates.
- Hold off on major structural changes until the rollout is closer to finished, since a two-week window means you’re looking at a moving target.
- If you do find and fix a genuine policy violation, know that recovery isn’t instant. Google’s systems need to reassess your site over time, and that can take months, not days.
The bigger pattern
Four spam updates in a single year is a real shift from recent history. Between this and the emphasis I covered in Google’s New AI Optimization Guide, the direction is consistent: Google is tightening enforcement around low-quality and manipulative content faster and more often than it has in years. If your site is built on solid technical SEO fundamentals and original content, an update like this shouldn’t be cause for alarm, but it’s a good prompt to double-check nothing’s slipped through the cracks.
Seeing sudden ranking drops or unusual fluctuations during this rollout? A Website SEO Audit can help identify whether it’s this update, a technical issue, or something else before you make the wrong changes.
