This was description of the Canonical URL ADVANCED PrestaShop module
Improve your website SEO and remove the duplicate pages from search engines. Canonical URL tag is recommended by all major search engines like Google, Bing, Yahoo, for resolving the duplicate pages issue.
The Canonical URL tag attribute is similar in many ways to a 301 redirect from an SEO perspective. In essence, you're telling the engines that multiple pages should be considered as one (which a 301 does), without actually redirecting visitors to the new URL.
Duplicate content issues occur when the same content is accessible from multiple URLs. For example, http://www.example.com/page.html would be considered by search engines to be an entirely different page to http://www.example.com/page.html?parameter=1, even though both URLs return the same content. Another example is essentially the same (tabular) content, but sorted differently.
Many sites have encountered issues with multiple versions of the same content on different URLs. This creates three big problems:
1. Search engines don't know which version(s) to include/exclude from their indices.
2. Search engines don't know whether to direct the link metrics (trust, authority, anchor text, link juice, etc.) to one page, or keep it separated between multiple versions.
3. Search engines don't know which version(s) to rank for query results.
When this happens, your site suffer rankings and traffic losses and engines suffer lowered relevancy. In order to fix these problems, you will need to use the Canonical URL tag.
