I should use the ‘not-listed’ post visibility option for blog posts. Per the mastodon docs:
Not listed: your post is still public but doesn’t appear on timelines. People can read it only if they are mentioned in it or if they go to your profile and scroll through your posts. Not listed posts are recognizable by an open padlock icon.
