Google’s September 2026 Spam Update: What It Is (and What It Isn’t)

Your rankings moved this week. You’re not imagining it.

On September 24 at 9:15 a.m. Pacific, Google released its September 2026 spam update. It’s rolling out globally. Every language. Right now.

Here’s the timeline. Google’s own Search Status Dashboard says this rollout could take up to two weeks, putting completion around early October. That’s longer than any spam update Google has run this year. March wrapped in under a day. June took roughly two days. August took about two and a half days. September is already set up to run well past all three.

Now here’s the part a lot of people are getting wrong.

This is a spam update. Not a core update.

Google hasn’t announced a core update for September. Its confirmed core updates in 2026 landed in March and May. So if your content is actually good, and you’re following Google’s spam policies, that ranking dip you’re seeing? It’s probably this rollout. Or normal volatility. Not some fundamental shift in how Google judges quality.

So what does a spam update actually do?

It sharpens Google’s spam-detection systems. Think SpamBrain, Google’s AI-powered spam catcher. Google hasn’t said exactly what it’s targeting this time, no tactic-by-tactic list, unlike August, when Search Engine Roundtable reported that Google had specifically excluded link spam and site reputation abuse from that rollout. For September, Google is staying quiet on scope, so the usual suspects, cloaking, scaled low-value content, and other tactics that break Google’s spam policies, are all fair game until Google says otherwise.

Here’s something most write-ups won’t tell you: this only hits organic search.

Running Google Ads? Your campaigns are untouched. Paid placements don’t care about spam updates. If you’re figuring out where paid fits into your strategy, check out our guide on what PPC actually is. New to Google Ads entirely? Start with our beginner’s guide.

Bottom line: don’t panic-rewrite your whole site.

Do this instead. Check Search Console. Find the pages that moved, and line up the timing against September 24. Review Google’s spam policies. If you’re violating one, fix it. Google’s systems need a few months to notice the improvement anyway.

If you’re clean? Ride it out.
