Canonical link is a solution often used by webmasters to counter duplicate content on websites. We deal with them when one website addresses several addresses - often very similar or exactly the same. Then we can use canonical to indicate to the search engine which of the links pointing to the same content should index.

The rel = “canonical” attribute is one of the ways to deal with duplicate content. It is placed on any HTML page between the <head> </ head> tags. Search robots begin to consider the page specified in the rel = “canonical” attribute as a priority (canonical). The canonical page will be displayed in the search, the reference weight and other characteristics of the pages with the same content will be transferred to it. Thus, if your site has identical or very similar content available at different URLs, you can use the attribute rel = “canonical” to specify the URL that is preferred for indexing.

The purpose of using canonical addresses is primarily to avoid duplicate content. Why? Because this is one of the most frequently detected by Google robots, and penalized with significant declines in the search engine position, the issue. In this case, however, we are not talking about reproducing content on our site from other sources, but also about internal duplication. It is nothing else than having the same content on different subpages of one website. According to the guidelines of Google, the most beneficial from the point of view of a search engine site will be one in which one URL address is dedicated to each one subpage. However, there are situations in which it is impossible - then we use canonical addresses, which allow eliminating the repetition of content for robots. It's a good idea to verify your page in this respect because the Google works that appear on it are browsing through each and every link in it.
