Google's September 2026 Spam Update Is Finished: Was Your Website Affected? A Checklist and Recovery Plan

In brief: According to Google's Search Status Dashboard, the September 2026 spam update began on 24 September 2026 and ended on 7 October 2026 (listed duration 13 days 16 hours; Pacific time). Other updates listed this year: the March core update (27 March–8 April), the May core update (21 May–1 June), the June spam update (24–26 June) and the August spam update (18–20 August). No new core update has been announced for October; SEO forums report unconfirmed volatility around 16–19 October, but the dashboard shows no matching entry. If your traffic fell in this window, diagnose calmly: is the drop really tied to this update, or to seasonality, a technical problem or something else? This article gives the checklist and recovery plan. Dates rely on the Google Search Status Dashboard record (23 October 2026).

What is a spam update?

Google's spam updates aim to reduce the visibility in search results of pages and sites that violate Google's spam policies (or to strengthen systems against them). The difference from core updates: core updates re-tune the overall assessment of quality and relevance, while spam updates target specific types of abuse. The main spam types in Google's documentation include scaled content abuse, site reputation abuse, expired domain abuse, cloaking and hidden text, link spam and duplicate/scraped content.

A spam update does not come with a penalty notice; affected sites usually lose rankings without seeing a manual action in Search Console. A manual action is a separate mechanism; check Search Console > Security & Manual Actions.

How do you tell whether you were affected?

1. Search Console > Performance: Compare 24 September–7 October to the previous period (or last year). Is there a sudden, lasting drop in clicks and impressions?
2. Page/query breakdown: Is the drop sitewide, in a specific section (blog, products, tag pages) or in particular queries?
3. Seasonality and campaigns: Compare with last year's pattern; holidays, campaigns or news periods can matter.
4. Technical events: Did a deployment, redirect change, robots.txt or noindex mistake or speed problem happen on those dates? (For redesigns see our guide to redesigning without losing SEO.)
5. Manual actions and security issues: Is there a notification in Search Console?
6. Index status: Is there an unexpected drop or exclusion in the Page Indexing report?
7. Competitors: Did competitors move on the same queries? There may be an industry-wide shift.

If the drop date does not overlap with the update window, the cause is most likely something else.

Risk checklist: Do you have any of these?

• Scaled, low-value content: Many pages with templated or mass-produced text that adds no distinguishing value (whether AI-generated or not). What matters is whether the page gives readers real benefit.
• Thin and duplicate content: Pages scraped from other sites, reworded, or repeated within your own site.
• Third-party “parasite” content: Third-party content published to exploit your site's authority, unrelated to the site's main topic.
• Link schemes: Bought/exchanged links, automated comment/forum links.
• Deceptive behaviour: Showing users and Googlebot different content, hidden text, deceptive redirects.
• Hacked content: Spam pages or injected links you haven't noticed. (Neglecting security updates can cause this: see our PHP2Shell article.)
• Expired domain use: Publishing content unrelated to an old domain's reputation.

A 6-step recovery plan

1. Diagnose, don't guess: Find the real cause with the steps above.
2. Remove or improve problem content: Merge, improve or remove low-value pages (with proper redirects). Make fixes that add real value, not half-measures.
3. Strengthen the technical base: Speed, mobile friendliness, structured data, correct canonical and hreflang. See our technical SEO with Next.js guide and multilingual site guide.
4. Strengthen trust signals: Author information, sources, current dates, contact and company information.
5. Be patient: Per secondary sources Google indicates recovery can take months; improvements may show up in a later relevant update.
6. Monitor continuously: Weekly Search Console tracking, monthly content audits.

AI-assisted content: when is it a risk?

AI-assisted content production is not forbidden in itself; but pages mass-produced to manipulate rankings without benefiting users can run into the spam policies. In practice: use AI for drafts, but add expert review, real data and original contribution; avoid producing hundreds of similar pages on every topic. For content planning see our service site content plan guide. For visibility in AI search, see our GEO guide.

What you shouldn't do

• Bulk deleting/changing as soon as you see a drop: Find the cause first.
• Believing services that promise a “quick fix:” There are no miracles for spam-related losses.
• Using the disavow tool indiscriminately: Not needed unless there is a real link problem.
• Changing things constantly: Constant rule changes during post-update fluctuations make diagnosis harder.
