Who can see my posts when I use hashtags?

When you add a hashtag to your post, the people you’ve shared your post with can also see it in that hashtag‘s feed. For example, if you share a post with a hashtag with the audience Friends, people you’re friends with can see your post in that hashtag’s feed.

If you use a hashtag in a post that you share to a Public audience, and allow people to follow you, your post will appear on your public profile and in that hashtag’s feed.
