Readability refers to how easy it is for visitors to read the content on your site. Factors that measure readability include:

  • Difficulty of the words included on a page
  • How much written copy you have on a page
  • How easy is it to scan the content on a page

Siteimprove uses these variables to determine how a page ranks, and using the Flesch Kincaid Grade Level scale, what demographics (based on age) should be able to successfully read and understand the content that’s written on a page.
