How to noindex topics within a specific category?

I’m pretty sure that’s not the case. I suspect making your off-topic stuff accessible only to people who are logged in is the way to go.

And here’s this from ask.discourse.com

Discourse does not currently include a built-in setting to automatically set noindex for all topics in a specific category if the category is still publicly viewable. The most reliable way to prevent indexing of topics in a category is to restrict the category’s visibility so only logged-in users can view it, but this may not fit your needs if you still want public access.

Key findings:

  • There is no core feature or admin setting to add a noindex meta tag to all topics in a specific category.
  • Adjusting robots.txt via the /admin/customize/robots setting will only affect the category listing page, not the individual topics inside that category (source).
  • A plugin would be required to automatically add noindex to topics in a specific category (source).
  • Other workarounds like “unlisting” or only showing categories to logged-in users either reduce public accessibility or don’t affect indexing by search engines (source).

Summary Table:

Method Effect on Search Engines Public Access
Restrict category to TL0 Blocks search engines & guests, not truly public :cross_mark:
Custom robots.txt Only blocks category listing, not individual topics :white_check_mark:
Plugin (custom development) Needed to add <meta name="robots" content="noindex"> to topics :white_check_mark:
Unlist topics Topics remain public & indexable if directly linked :white_check_mark:

If a plugin solution is required and you are hosted by Discourse (Pro/Business/Enterprise), you should contact team@discourse.org to discuss your needs, as hosted plans do not allow custom plugins directly but may offer professional services or alternative solutions.
