Quick answer: On October 26, 2026, Google updated its “Prevent user-generated spam on your site and platform” documentation to explicitly cover tools that let users publish shared pages, generated content or web apps. A new section, “Only index content meant for Search,” tells platforms to apply noindex by default to pages created for sharing, collaboration or utility rather than for discovery in Search.
What happened
Google’s user-generated spam guidance has long covered forums, comments and hosting platforms. The update widens it to a newer category: AI tools, app builders and other services where users can generate a page and share it with a public link.
Google’s advice is that these services should separate content meant for public discovery from content meant only for direct access. Where a page exists to be shared by link, the platform should keep it out of Google’s index.
What Google recommends
- Noindex by default: Use a robots meta tag or X-Robots-Tag header on shareable pages, generated outputs and interactive tools that are not meant for Search, or block crawling in robots.txt.
- Verify in Search Console: Verify the site or subdomain so you receive manual action and security alerts.
- Monitor for abuse: Watch Page Indexing and Search performance reports for unexpected spikes in indexed pages, impressions or off-topic queries.
- Set platform alerts: Track sudden jumps in new public pages or a small number of users producing a large share of indexable URLs.
Why it matters
Spammers have increasingly abused trusted AI and productivity platforms, publishing pages on their domains to borrow authority and rank quickly. This site has covered spammers using public NotebookLM pages to spam search results, for example. Google did not name specific products, but SEOs including Lily Ray speculated the guidance could apply to AI-generated sites, shared chatbot pages and similar tools. Marie Haynes asked whether it signals future manual actions against platforms that do not act.

- Set up Search Console alerts and monitoring for sudden indexing spikes.
FAQ
Does this affect normal blogs and business sites?
Mostly no. It targets platforms where many users can create pages. A typical business site is not affected unless it hosts user-created pages.
Is noindex required?
It is a recommendation, but platforms that allow spam to be indexed at scale risk manual actions affecting the whole site or subdomain.
