Readability: Why do some of my pages have no readability score?

In your Readability Test Results overview, you may have encountered pages displayed as having no readability score. This article is intended to inform you about a few scenarios where no readability score was generated. 

Possible scenarios where some of your pages have no readability score:

• Using a readability test that has a condition stating that a readability score will not be calculated on content below a certain amount (Coleman-Liau, SMOG and Gunning Fog).
  
  
  


• The structure of the page is very different from what Siteimprove's training model is based on. In other words, the machine learning tool does not identify any content on the page.
  
  
  


• No content has been identified to calculate a score. This is particularly the case if there is only a table with links and very short text, bullet lists with links and ultra short texts.
  
  
  


• In some cases, there may be text on a page which is not identified as text due to a lack of or incorrect HTML markup.

The readability tests that Siteimprove uses are not web specific. Many web pages do not contain anything resembling a sentence or a paragraph making it impossible for the machine learning tool to calculate a score that would be of use. Do not worry too much about the "No readability score" bar, focus rather on pages where Siteimprove has calculated a readability score. Those pages with a readability score are the pages that you should ensure work for your end users.
