Google may penalize sites where users can publish pages
Updated spam guidance warns platform owners to watch what their users get indexed.
Google has updated its guidance on preventing user-generated spam, and the new wording aims squarely at sites that let other people publish things. Marie Haynes flagged the change, Barry Schwartz reported it, and Lily Ray called it a clue about what Google will target next.
The update adds a section called "Only index content meant for Search". According to Marie Haynes, it covers "platforms and tools that let users publish shared pages, generated content, or web apps" as well as "generated outputs, or interactive tools". It also tells owners to watch Search Console for alerts if Google issues a manual action against the site or detects security issues. A manual action is a penalty applied by a human reviewer at Google, not an algorithm, and it can remove pages or a whole site from search results.
What Google tells site owners to check
The guidance says to check the page indexing report and the Search performance report regularly for unexpected spikes in indexed pages, impressions, or queries that do not match what your platform is for. Marie Haynes says it also mentions looking for a small number of users generating a large share of indexable URLs.
She reads this as Google shifting the work of policing content onto the people who build the tools. If your site lets anyone create a page, you are responsible for what ends up in Google.
Why it is happening now
Marie Haynes points to conversations from Muse, and before that ChatGPT and Claude, getting indexed, plus people building ChatGPT sites that have deceived others once indexed. Lily Ray's first thought was Claude artifacts, ChatGPT pages and sites, Facebook posts and similar tools that make it easy to produce indexable user content at scale. Google does not name any specific tool in the document.
Lily Ray also reads the timing as a signal. Documentation changes like this usually mean Google is already dealing with the problem at scale, and that enforcement may follow.
What to do
If nobody except you can publish on your site, there is nothing to do here. If your site has user profiles, a forum, a comments section, a review feature, or any tool that spits out a public page, open Search Console, click Pages, and look at how many pages are indexed. A sudden jump you cannot explain is the warning sign described in the guidance. Then open the Performance report and scan the queries. Searches that have nothing to do with your business mean something is getting indexed that should not be.
The fix in those cases is to stop the machine-made or user-made pages being indexed, rather than waiting to find out whether Google agrees they belong in search.
Google has updated its spam policies (again!) to warn sites that allow users to publish "shareable pages, generated outputs, or interactive tools," as this could be treated as spam.
Sounds to me like Google is putting the burden of curation onto the tool makers now.
