Last I counted, there were over forty thousand plugins in the WordPress plugin repository. (Yes, I count them. What? It’s a hobby, don’t judge). Of those, I’m guessing there are only about 2% that are earning their authors money in some way, whether by asking for a kindly donation from users, upselling them to premium add-ons and features, serving ads, or even displaying a random kitten picture at 5¢ per click. If you want to join this small-but-merry band of creators, or you’re looking to up your plugin marketing game and tickle your bottom line, this post is for you.
