Google’s September 2026 spam update began rolling out on 24 September and was marked complete on 8 October, according to Google’s Search Status Dashboard. If your traffic held steady, you do not need to change anything. If it dropped, the first job is to find out whether the update is really the cause, because several unrelated things also moved in October.
What happened, in order
- 24 September: the spam update starts rolling out worldwide, in all languages.
- 1 October: Google updates its guidance on using generative AI content, adding references from its Search Quality Rater Guidelines about content made with little effort, originality or added value. This is a documentation change, not a separate ranking update.
- 8 October: Google marks the spam update complete. Industry coverage described it as a routine spam update rather than one that introduced new policies.
- 21 to 26 October: more documentation updates, including how to control what you share with Google Search (21 October), word separation in URLs, hyphens versus underscores (23 October), and preventing user-generated spam (26 October).
Was your site actually affected?
A traffic change during a rollout does not, on its own, prove the update caused it. Work through these checks in order.
- Compare the right dates. In Google Search Console, compare clicks and impressions from 24 September to 8 October against the previous period and the same weeks last year.
- Look at the shape of the drop. A spam-related demotion often hits a group of similar pages or a whole folder. A sitewide slide across every page points elsewhere.
- Open the Manual actions and Security issues reports. If either lists a problem, that is your answer, and it is not the algorithm.
- Separate Search from Discover and News. In October, site owners reported Discover drops and stale Google News results. Those are different surfaces from ordinary search results.
- Allow for reporting lag. Around 11 October the Search Console performance report was reported to be running more than 60 hours behind before catching up. A “drop” on the last two days of a report is often just missing data.
What about a core update?
As far as we could find on 28 October, Google had not announced a new core update on its dashboard. The last confirmed core update before October was the May 2026 core update. Forums did report ranking volatility in late October, but volatility is not a confirmed update. Be wary of anyone who labels a drop “the October core update” without a dashboard entry to point to.
What Google’s spam policies actually target
Google’s spam policies cover a defined list of behaviours. The ones small businesses most often run into are:
- Scaled content abuse: producing many pages mainly to rank, whether they are written by people, by AI or by both.
- Site reputation abuse: hosting third-party content on a trusted site to borrow its ranking strength.
- Expired domain abuse: buying an old domain to push low-value content.
- Link spam: buying or trading links to manipulate rankings.
- Cloaking and sneaky redirects: showing search engines something different from what visitors see.
- Hacked content: pages injected into your site by attackers, often selling pills, casino or counterfeit goods.
A practical checklist
- Audit pages made at volume. Dozens of “digital marketing in [city]” pages with only the city name swapped are the classic risk. Merge them, rewrite them with genuinely local detail, or remove them.
- Use AI as an assistant, not a factory. Google’s guidance says AI can support research and structure, and also warns that generating many pages without adding value for readers may violate its scaled content abuse policy. Check every fact, add real examples and experience, and put a named author on the page.
- Review your backlinks. Paid links and link exchanges are the risk. A disavow file is rarely needed and should be a last resort for a clear pattern of manipulative links.
- Clean up user-generated spam. Google’s 26 October update advises keeping user-created pages that are not meant for Search out of the index and watching for abuse early in Search Console. On WordPress, that means moderating comments, closing spam registrations, and checking that author and tag archives are not filling with junk.
- Scan for hacked content. Search your site for pharma, casino or unfamiliar pages, update plugins and themes, and remove accounts you do not recognise.
- Keep URLs clean. Hyphens between words are the recommended separator. There is no reason to change existing URLs just for this, but use hyphens on new pages.
- Give every page one clear purpose. Two pages competing for the same query is a quality problem on its own.
What not to do
- Rewrite the whole site in a panic before you know what was affected.
- Delete pages in bulk without looking at which ones bring enquiries.
- Pay for a “spam recovery package”. Nobody can guarantee a recovery.
- Publish hundreds of AI-generated pages to “make up” lost traffic.
A simple 30-day plan
Week 1: diagnose using the checks above and write down what you find. Week 2: fix security, hacked content and spam in comments or forms. Weeks 3 and 4: consolidate or improve your weakest pages and strengthen your best ones. Then wait and measure. Improvements are not always reflected immediately, so judge progress over weeks rather than days.
Frequently asked questions
Does Google ban AI-written content?
No. Google’s updated guidance says AI can help with research and with structuring original content. The problem is producing many pages that add no value for readers, which can fall under its scaled content abuse policy. It also advises checking AI-generated content for accuracy before you publish.
My traffic fell on 12 October. Was it the spam update?
The update had finished on 8 October, so look first at other causes: reporting delays, Discover or News volatility, seasonality, a site change or tracking problem.
Do I need a disavow file?
Usually not. It is only worth considering if you have a clear pattern of paid or manipulative links that you cannot get removed.
The short version
Check before you change. Confirm the dates, confirm the pattern, rule out security and reporting problems, then fix real quality issues. A site with original, useful pages and a clean technical base has little to fear from a spam update.
