How much effectiveness can you get from the exitintent popup form you placed in your blog? Does it makes sense to your customers to see it when they leave your page? Or you just placed to see if you get lucky and get some signups? Codepen.io does not like exitintent forms, but has a clever way to ask you to signup when you are a) nonlogged and b) tap CTRL+S if you want to save your project. Have you think about using keyboard shortcuts your audience might already doing to get their clicks there where you want?
