Google's September 2026 Spam Update: What Got Hit

Google’s September 2026 spam update started rolling out on the 24th, and the first wave hit hard on the 25th through 27th. Search Engine Roundtable and other trackers flagged unusually high SERP volatility over that weekend — the kind of swing that tells you a spam update isn’t just a routine housekeeping pass. Google confirmed a full rollout window of about two weeks, so if you saw rankings jump around on that Friday-to-Sunday stretch, you’re not imagining it.

What makes this one worth paying attention to, beyond the usual “another spam update dropped” news cycle, is the scope. This update explicitly targets a wider range of spam tactics than prior passes, and it names AI-generated and programmatic-generated content as a specific focus. That’s a meaningful signal for anyone running large-scale content operations, because it draws a line between programmatic content done well and programmatic content done as a volume play.

Why “programmatic” isn’t the problem — unedited output is

Google has said for years that automatically generated content isn’t automatically penalized. What gets penalized is content generated primarily to manipulate rankings, with no meaningful human oversight, editorial judgment, or added value. The September update appears to be enforcing that distinction more aggressively than before.

If your programmatic pages are templated location pages, comparison pages, or product variant pages that were built once, populated with a data feed, and never touched by a human editor again, that’s exactly the pattern this update seems built to catch. If your programmatic pages are built on a solid template but each one gets reviewed, has original data or commentary layered in, and gets updated when the underlying facts change, you’re in a fundamentally different category — even though both approaches technically use automation.

The practical test Google keeps pointing back to: would this page exist, in this form, if search engines didn’t exist? If the honest answer is no — it exists purely to occupy another SERP slot — it’s a target.

What to actually check this week

Start with a straightforward audit of anything on your site that was generated at scale, whether by AI tools or by scripts pulling from a database or feed. Look specifically for:

• Pages with no human-written intro, context, or point of view — just a template wrapped around raw data
• Doorway-style pages that all funnel to the same conversion path with only a keyword swapped in the title and header
• Thin location or category pages that duplicate structure across hundreds or thousands of URLs with negligible unique content
• Any page where you genuinely can’t say who wrote or reviewed it

For each of those, the fix isn’t necessarily deletion — it’s often adding the human layer that was missing: a real author, an updated data point, a paragraph of actual analysis, evidence that someone with expertise looked at the page before it went live. That’s the substance of E-E-A-T signals, and it’s what separates a defensible programmatic strategy from one that’s exposed every time Google tightens enforcement.

Monitor before you panic

Because the rollout runs roughly two weeks, don’t overreact to day-three volatility. Track your rankings daily across a representative set of pages — especially your programmatic and AI-assisted sections — and separate genuine algorithmic reassessment from normal noise. If a specific template or content type is losing visibility consistently as the rollout progresses, that’s your signal to prioritize edits there first rather than across the whole site.

This is also a good moment to check whether your internal linking and site structure are inadvertently amplifying thin pages — a template flaw that a manual review might miss but that becomes obvious once you’re comparing which page types lost ground.

Spam updates like this one are Google recalibrating what “at scale” is allowed to mean without human judgment attached. If a meaningful chunk of your site was built to fill keyword gaps rather than answer real questions, it’s worth having someone audit the whole template system before the next rollout, and that’s the kind of structural review we do through our programmatic SEO service.
