Making sense of the results
It should be noted these results are a guide only to help speed up the process of finding content weaknesses in your site. Having a higher % of duplicate content still requires analysis of that page and taking a considered approach to how you deal with it. If you are unsure, it is best to consult with a professional SEO before taking any drastic action.
Each page in the expanded section shows a % value in the right column. This % value is the % match of duplication against the main page for this expanded section.
In this example below, we see the 'visit' page has a 42.65% similarity match with the home page.
