Also, consider that if, like many other pages, this one just had a few soundbites and a big "Sign Up" button, the conversion rate to signups may be higher, however the conversion rate to paying customers is another matter altogether.
One very small change that you can make to get more people INTO the long-form copy is to "lead with the pain" in that paragraph. For example, in the opening paragraph, you open with "Make your AngularJS, EmberJS, or BackboneJS website Crawlable by Google" and then after some picture-painting for the reader, you go in for the kill with "Right now Google can't see your website. You could change that in just a few minutes."
If you swap those two sentences, the entire package becomes a lot more persuasive. There's a boatload of similar opportunities through the rest of the page that should be pretty easy to spot, too.
Congrats on finding your focus and pushing ahead!
