Canonical Tags for ranking


How canonical tags can be used for back link?

Canonical tag                     : In general canonical tags are used for avoiding duplicate content issues.
Canonical tag use               : If two or more pages in your site have similar content there may be possibility of getting penalized by search engines for duplicate content issue, search engines gets confused in deciding which page to be displayed in their SERP. In that case you can use canonical tag for suggesting search engines about which page to be displayed in their SERP.

Canonical tags are also mentioned as similar to a 301 redirect.

If canonical tags are similar to a 301 redirect, then they will pass the link juice from the page which has the tag to its original (canonical page).

Consider two domains uvw.com and xyz.com

Host the site in both domains. Both sites can have similar content and similar pages.

Add canonical tag to every page of uvw.com.

For example:

Assume both sites have pages

Uvw.com
Uvw.com/page1
Xyz.com
Xyz.com/page1

Mention xyz.com as the canonical page in source code of uvw.com

<link rel="canonical" href="xyz.com">

Mention xyz.com/page1 as the canonical page in source code of uvw.com/page1

<link rel="canonical" href="xyz.com/page1">

This makes xyz.com as the original content and they will be displayed in SERP and not the pages of uvw.com. Now the authority, page rank of the domain uvw.com is gained by xyz.com
