Step 2.3: Canonical Tags
Basic Concepts | On-Page | Canonicalization
We can’t talk about canonicalization without talking about canonical tags. Canonical tags are pieces of code that sit in the head section of the source code of a page. They are not visible to users and they contain a link.
That link tells Search Engines, what the ‘canonical’ URL is of the page, in case it can be accessed from multiple URLs.
You can also use a link to another page altogether if the content on the page is largely borrowed (duplicated) from the page being linked to.
Canonical tags look like this:
<link rel="canonical" href="https://raptor-dmt.com/">
The URL in the above code is the ‘canonical link’ of the canonical tag.
Every page should have a canonical tag on it.
