Content: Exact Duplicates

Pages that are identical to each other using the MD5 algorithm which calculates a ‘hash’ value for each page and can be seen in the ‘hash’ column.

This check is performed against the full HTML of the page. It will show all pages with matching hash values that are exactly the same.

Exact duplicate pages can lead to the splitting of PageRank signals, crawling inefficiencies and unpredictability in ranking.

How to Analyse in the SEO Spider

What Triggers This Issue

This issue is triggered when pages are identical to each other.

How To Fix

There should only be a single canonical version of a URL that exists and is linked to internally. Other versions should not be linked to, and they should be 301 redirected to the canonical version.
