Your blog should have a decent UX.

I will summarize this in the 3 Ifs:

If it takes >= 3 seconds to load your blog,

If it isn't mobile-friendly and user-friendly,

If it looks like a bunch of hot mess,

Then expect your visitors to hit the Back button.

Luckily, If you are using Bear (the blogging service that this site is hosting on), then it has already done all the job for you.
