One simple thing to do to get more comments and engagement on your blog is to say Thank You to your commentators.
“Thank you” can really be an incredibly powerful pair of words in blogging. I think anyone who takes his/her time to read your posts and drop a comment deserves it. You can simply reply to those comments and say those words like others do.
But a better way to do it, probably with a reward is MyCommentAuthors. It’s a simple free WordPress plugin that nicely and effortlessly generates a list of your commentators for a chosen month.
