Where is the robots.txt file?

You can find the file at the root of your marketplace address. For example:

If your marketplace address is https://example.mysharetribe.com, your robots.txt file can be found at https://example.mysharetribe.com/robots.txt.
If your marketplace address is https://www.example.com, your robots.txt file can be found at https://www.example.com/robots.txt.

What does the robots.txt file contain?

The robots.txt file for Sharetribe marketplaces allows Google (and other search engines) to index all your marketplace pages. Some bots might be restricted for performance reasons.

Your robots.txt file would look something like this:

#
# Hello bot! There are some routes that need authentication. You should avoid them :)

Is it possible to edit the robots.txt file?

If you customize your marketplace with code, yes. Otherwise, it is impossible to edit the robots.txt file for a specific marketplace with the no-code solution.
