Questions about title and site description admin setting


I am new to Discourse and am setting up a new forum. I have a few questions about the title, long and short site description:

  1. Where do people see these info in forum?
  2. Will search engine pick up these info and use it in the search snippets?
  3. Is there an optimized word limit for the descriptions?

I appreciate if anyone has any examples for reference. Thank you very much!

I have found where the long description go, it’s on the About page. I also found that the long site description will be used for URL link preview description. I am still confused about the short description though. :frowning:
