What is canonical? This is a tag that is used to mark primary source pages. It is useful if the site has several pages with the same content. With this attribute, we can show the search engine which of them is
the main one and should be indexed.
Next, we’ll discuss how to set up email data canonical pages, when this is necessary, and how the canonical tag differs from a redirect. What is canonical used for? Canonical is a tag that is primarily used to exclude duplicates from indexing. It tells the search engine that a specific URL should be shown in the search results instead of the duplicate page. However, sometimes non-canonical URLs may still appear in the search results if the system considers them more relevant to the user’s query. This can happen if the
content is noticeably different
from the original source. Therefore, canonical is not an order for the search engine, but only a recommendation.They increase the size of the site, and indexing takes longer. Plus, identical pages get into the index, but robots can scan other important elements last. Competition between URLs with almost identical content. If you think that you can take two places in the search results at once, this is not true. It is more likely that the page you did not plan to promote will appear in it. Link weight is lost.
Because some external links can up to this point everything seems simple be duplicated, link weight is diluted. As a result, the main page that is important for you to promote does not receive it. Where does duplicate content appear on a site in the first place, for which canonical must then be used? It is important to understand that duplicates are not necessarily completely identical content. Sometimes it can simply be very similar. This situation often
occurs in online store catalogs. For ew leads example, they may have filters that allow a person to change the order and number of products displayed. In fact, the content there remains the same, only its location changes. Another option is that the catalog contains a short description of the products. But the exact same description is also in the product card. It turns out that the content is also duplicated.
