On 26 October 2026 Google revised its guide to preventing user-generated spam. According to the change log of the Google Search documentation, it now covers how to keep pages out of the index that exist only for sharing or collaboration, and how to spot abuse earlier in Search Console. This matters to anyone whose website lets users publish content: web apps, SaaS products, forums, review portals and comment sections.
What happened?
Google updated its page on preventing spam in user-generated content; the page is dated 26 October 2026. This is a change to the documentation, not a ranking update. Google is not announcing new rules or penalties; the guide describes recommendations.
Among other things, the guide covers:
- Index only what is meant for search: Pages created for direct sharing, for collaboration or as a tool should stay out of the index with
noindex(robots meta tag or theX-Robots-TagHTTP header). Alternatively, crawling can be blocked in robots.txt. - New users without a reputation: Their posts can start out as
noindexand be released once the user has proven trustworthy. - Links in other people's content: These should be marked with
rel="ugc"orrel="nofollow". - Monitoring: If you verify your website in Search Console, you receive emails about manual actions and security issues. The guide advises checking the page indexing report and the performance reports regularly for unexpected spikes, for example in indexed pages, impressions or search queries that have nothing to do with what you offer.
- The basics: A published abuse policy, moderation of suspicious posts, blocking conspicuous IP addresses and a check at sign-up, for example with reCAPTCHA or a similar tool.
The page itself does not say which of these points are new. We rely on the entry in the change log and the current wording of the page.
What does this mean for your business?
For a classic company website without comments, a guest book or user profiles, nothing changes. A simple contact form whose submissions are never published is not affected.
It is a different story if visitors can create content that gets its own publicly accessible URL: profile pages, shared documents, project pages, forum posts, reviews, classified ads. Spammers can abuse pages like these for links and advertising. In the end the reputation of your whole domain is at stake, and in the worst case Google can impose a manual action. If you run a web app or a SaaS product, plan for this risk early, not after the first incident.
What should you do now?
- Check whether users create publicly accessible pages. If they do not, there is nothing more to do.
- Decide what belongs in the index. Pages that only serve sharing or working get
noindex. Content with real subject value can stay indexable. - Mark links in user content (
rel="ugc") so they do not count as a recommendation from your domain. - Limit new accounts and posts: approval or reputation before indexing, protection at sign-up, a way to report abuse.
- Verify your site in Search Console and look at the page indexing report once a month. A sudden sharp rise in indexed pages is a warning sign.
On an existing website, your developer or agency can usually implement points 2 to 4 with manageable effort.
What is still open?
Google names no deadlines and no consequences beyond those already known. Whether the change is linked to an upcoming spam measure is not documented, and we do not speculate about it. This article is as of 27 October 2026.
