Google’s user-generated spam guide now tells platforms to noindex shared pages

Google updated its guide to preventing user-generated spam on 26 October 2026. A new section asks any service that lets people publish shared pages, generated content or web apps to keep those pages out of Search unless they are meant to be found there.

Google asks platforms to block indexing by default

The section is called “Only index content meant for Search”. It asks each platform to decide which user pages are for public discovery and which are only for people who have the link. Google gives three examples: shareable pages, generated outputs and interactive tools.

For pages made for sharing, teamwork or a one-off task, Google recommends a noindex rule as the default. It can be set with a robots meta tag or an X-Robots-Tag header. Blocking crawling in robots.txt is the other option Google lists. In its documentation changelog, Google says the aim is to help platforms “detect spam earlier”.

Search Console reports become the early warning

The second change is about monitoring. Google wants platforms to verify their site or subdomain in Search Console, so they get emails about manual actions and security issues. It also tells them to watch the Page Indexing and Search performance reports for sudden jumps in indexed pages, impressions or queries that do not fit the service.

Platforms should also count how many public pages users create. Google suggests alerts for a spike in new pages and for cases where a few accounts produce a large share of the indexable URLs.

Lily Ray and Marie Haynes link the change to AI tools

Google did not name any product. On Search Engine Roundtable, SEO consultant Lily Ray suggested the guidance could cover shared AI chat pages and Claude artifacts. Marie Haynes asked whether manual actions for AI and app-building tools could follow. Google has not answered either point.

The update comes a month after Google’s September 2026 spam update. Google has also said it does not ban AI content but punishes missing human work.

A brand that runs a public quiz, calculator or AI chat on its own domain can check one report today. In Search Console, open Page Indexing and look for user-created URLs marked as indexed. If they are there, a noindex tag on that page template is the fix Google now describes.
