Google’s September 2026 Spam Update Explained

Google began rolling out its September 2026 spam update on 24 September. The update applies globally and to all languages, and Google says it may take up to two weeks to complete. At the time of writing, the rollout is still under way.

If your rankings or organic traffic have dropped, the timing makes the update worth investigating. It does not, on its own, prove that Google has identified spam on your website. Here is what we know and how to assess what has happened before making changes.

What is the September 2026 Spam Update?

Google uses automated systems to detect spam in Search. A spam update is a notable improvement to those systems, which Google announces on its Search Status Dashboard. Its September 2026 announcement confirms the start date, worldwide scope and expected rollout window, but does not identify a particular tactic or spam policy targeted by this update.

This distinction matters when deciding what to do next. Google has not said that the September update specifically targets AI content, links or any other single practice. An audit should therefore be based on your site’s data and Google’s published policies, rather than an assumed cause.

This is the fourth announced spam update of 2026, following updates in March, June and August. For more context on previous releases, see Google’s history of algorithm changes.

Does a Rankings Drop Mean Your Site Has Been Penalised?

No. A drop during the rollout is a reason to investigate, not a diagnosis.

Start by distinguishing between a fall in rankings, a fall in organic clicks, and a fall in reported traffic. They can have different causes. If clicks have fallen while impressions and average position remain fairly stable, look more closely at changes in search demand or click-through rate. 

If Search Console shows a sharp loss of impressions and position across a group of pages, investigate those pages and queries in detail. If the decline appears only in analytics, check that tracking still works as expected.

Also review recent website changes. A migration, altered redirects, an accidental noindex tag, a changed canonical URL, or removed content could explain a sudden decline. The announcement date is useful context, but timing alone cannot establish that the spam update caused a loss.

How to Investigate a Drop in Google Search Console

A structured comparison will tell you more than repeatedly checking a handful of keywords. Use the Performance report in Google Search Console to compare the period after 24 September with an equivalent period before the update. Because the rollout is ongoing, treat early findings as provisional.

Look at:

• Pages: Is the decline concentrated in certain templates, sections or individual URLs?
• Queries: Have you lost visibility for a particular topic, or across unrelated searches?
• Search type, country and device: Is the change limited to one part of your audience?
• Clicks, impressions and average position: Are people searching less, clicking less, or seeing your pages lower in the results?

Keep a record of when the decline began and which pages were affected. Cross-check this against site releases, content changes, indexing reports and any wider pattern you can see in the search results. If only one section has fallen, review that section first. A site-wide rewrite based on a small set of affected URLs risks obscuring the actual issue.

What Should You Review if Rankings Have Fallen?

Google advises sites that see changes after a spam update to review its spam policies. Pages or sites that violate those policies may rank lower or disappear from results. That guidance makes a policy review a sensible next step once you have ruled out straightforward technical and measurement issues.

Focus on practices that are present on your website, rather than working through a generic list of SEO fixes. Questions to ask include:

• Were large numbers of pages published mainly to capture keyword variations, with little original value for readers?
• Are any pages substantially copied, lightly rewritten or assembled without adding useful information?
• Do titles and on-page claims accurately reflect what visitors will find?
• Has third-party content been published on the site primarily to take advantage of its existing ranking signals?
• Are there pages, redirects or links whose main purpose is to manipulate search results?

For example, Google defines scaled content abuse by its purpose and value, not simply by whether AI was used. Producing many pages mainly to manipulate rankings, where they offer little original value, is the concern. A useful review looks at the actual pages, how they were produced and whether they satisfy the visitor’s needs.

How Should You Respond if Rankings Have Fallen?

First, check for issues that need fixing now, such as an accidental noindex tag, broken redirects or a tracking problem. You do not need to wait for the rollout to finish to correct a confirmed technical issue.

If there is no clear technical cause, monitor the affected pages and queries while the update rolls out. Rankings can fluctuate during this period, and some pages may regain visibility as the results settle. Google says the rollout may take up to two weeks, so avoid making broad content changes based on a few days of data.

Once the rollout is complete and the pattern is clearer, investigate any decline that persists. Compare affected pages with those now ranking above them and consider whether your content answers the search query as clearly and usefully as it could. A lasting drop does not automatically mean your site has violated a spam policy.

If your review uncovers a problem, address its cause rather than rewriting everything at once. Improve pages that offer little original value, consolidate repetitive content and correct misleading claims. Record what you change and when. Where a site has violated Google’s spam policies, improvement may take months while its systems learn that the site complies.

What if Your Rankings Have Not Changed?

Continue monitoring the pages and queries that matter to your business while the rollout completes. Stable performance today does not tell you how the remainder of the rollout will affect your site, and normal ranking movement can happen for reasons unrelated to an announced update.

The most useful preparation is an honest review of any content or SEO practices you would struggle to justify to a visitor. Keep pages accurate, maintain a sound technical setup and make sure each page serves a clear purpose.

The Key Takeaway

Google has confirmed the September 2026 spam update, but has not disclosed a specific target for it. If your rankings have dropped, use Search Console to establish where the change occurred, check for technical or tracking causes, and review the affected content against Google’s spam policies.

Make changes where the evidence points to a problem, then continue monitoring performance as the rollout finishes and after any changes you make.
