Getting search engines to accurately describe your site?

Hey all-

So I don’t know why or how to fix it, but search engines listing my site lists the info under the link as “the personal website of Confessions of a TV Harlot” instead of the info I use to describe my site (Rants, reviews, gossip, and news about what you watch.)

My site is at https://www.tvharlot.com .

How do I fix this so that my subtitle of my blog is what shows up in search engine searches, rather than that bland description?
