Complete page duplicates

In this report you will find a list of pages on which the complete HTML code is identical to the code of one or more other pages.

Unlike the "Duplicate content" analysis, this analysis looks at the complete HTML content of the page, including links, images, forms, etc., and not just the text.

Duplicate HTML pages of this kind are cases of duplicate content that clearly have a technical origin.

Why you should avoid duplicate content:

Duplicate content is very problematic from an SEO perspective and should be avoided at all costs. If you have a number of pages with the same content, search engines such as Google have to decide which of these URLs is the most relevant for the keyword in question and should be displayed in the search results.

As a result, it may happen that the "wrong" URL is selected. In addition, duplicate URLs can spread positive ranking signals such as backlinks across the different URLs. This can cause the individual pages to rank lower than if these signals were consolidated on one URL.

How to fix these problems:

In order to fix these problems, you first have to find out what is causing the duplicate HTML pages. Frequent causes are:

• Your pages can be accessed both with and without the "www." in the URL. From a technical point of view, this creates duplicate content, as the same content can be found under two URLs. You can solve this problem by setting up a site-wide 301 redirect to the preferred URL variant. You can find more information on how to do this in our wiki. With the free Seobility Redirect Checker, you can easily check if your website redirects to the preferred URL variant correctly.
• URL parameters, such as session IDs, that do not change the content of the page. You can solve this problem by adding a canonical tag to these pages, which links to the original version of the page without any parameters.
• Multiple product pages for very similar product variants in an online shop that differ only in size, for instance. (This analysis filters out such minor differences in numbers). Instead, use just a single product page with drop-down menus for sizes etc.
