In the web analytics world, part of understanding how useful or effective your site pages are comes from how far visitors scroll down the page (a.k.a. the percent page viewed). This is particularly interesting for content producers like bloggers, news outlets, or any other text-based vertical. It does not matter how many people visit your blog post if most of them do not scroll far enough to see the call-to-action. How will you know if the content is not engaging enough or the juicy bits are regularly kept below the fold if you don’t understand how your site’s users regularly view the page?
