Hi. Is there any way how to prevent a hosted streamlit app from being indexed by Google?
Usually it would just be a case of adding
<meta name=”robots” content=”noindex,nofollow”> to the header but with access to the main HTML being limited I couldn’t find a way how to add this in my app.
I have the same exact question.
I will cross post on Discord to get some more eyes on it !
From @randyzwitch
In most cases, Streamlit apps aren’t actually indexed…this is something we’re trying to fix though for Streamlit Cloud! If you are using a self-hosted app, adding a
robots.txtfile for noindexing should work like any other website
Does this mean that all Streamlit Cloud apps are indexed ?
Thanks as always @randyzwitch
It actually means the opposite! Streamlit Cloud apps are currently not indexed. Making apps indexable is a Q4 2022 roadmap item: https://roadmap.streamlitapp.com/#apps-are-indexed-by-google-scoping-speccing
To add a subtlety to @snehankekre 's answer… there’s nothing explicitly to prevent an app from being indexed right now, though on a practical basis is doesn’t work well currently. At some point, we will fix that (per Snehan’s comment), but neither should be considered the basis of securing your app from the public.
robots.txt will suggest to search engines to not index, and password-protection will keep search engines from actually indexing the content.
Thank you both for the help
