What is a Canonical Tag?

A Canonical URL is an HTML tag in the <head> section of a web page. The best way to show the search engine which page URL has the original content. The search engine crawls and indexes the original page and does not consider duplicate pages based on the canonical URL.

In other words, the canonical tag gives the search robots information about which page they should put in the search index and display it in the search results for user queries. If you have two pages with identical content, the presence of a canonical tag will tell which page is important and primary and which is a clone/duplicate. The search engine will not include the duplicate in the search engine index. A typical canonical URL example:

Cases When Tool is Needed

Canonical URLs help search engines combine information about individual URLs (such as links to them) into a single authoritative URL. Also, if you distribute your content for publication on a different domain, canonical URLs help anchor page rankings to your preferred URL.

With this tag, you can emphasize pagination pages, mobile pages, or local pages. These might be archive pages or service pages important to your site, but don’t give them link weight or want them to be not visited by users. If duplicate versions of pages you can’t remove and don’t want them in the search index, implement Canonical on the website.

We recommend reducing this issue and the number of such pages or setting the Canonical extension correctly. Implementation will help avoid an error, Canonical points to redirect or Canonical is a relative URL.

The canonical URL is the page’s address from the group of duplicate pages, which is a priority and is added to the index by the Google search engine.
You can instruct search engine crawlers using the rel=canonical to allow them to include the webpage in the index or not. You can also create these instructions via the Robots meta tag in your href HTML pages <head> section or the X-Robots-Tag in the HTTP header.
Canonicalized URL is used when the same page content is displayed at a different URL and when the same content is available at a different URL but in a different version.
The canonical tag in the source code specifies which URL the search engine robots prioritize. It will avoid duplicate content because all original pieces of content should be accessible only by one URL.
