An Introduction To Canonical Tag


Before starting anything new, I just want to talk a little bit about redirects and canonicalization, duplicate web URLs and other things that we used to perform for our website. We commonly think that a page with WWW is same as a page with non-WWW. Yes, it appears like same and it has same content as non-WWW page, but in the prospect of search engine bots, these pages are dissimilar.
Well now we are on our topic that is Canonicalization. It is a basic process for selecting the most appropriate URL for our website, it is frequently used for the home page of our website. Like we have different URL choices, such like
•    www.example.com
•    Example.com
•    www.example.com/index.html
•    Example.com/home.php

Canonical TagThese Web URL`s look same but technically these are different. For search engine bots these URL`s are different and we try to select the best URL that looks like the best representative of our website.  The canonical tag is generally termed as a better solution of 301 redirect for cleaning the issue of Duplicate content.  Duplicate Content issues occur when search engine bots or spiders thing that a webpage has two or more URL`s  and these have same content. The search engine bots consider this thing as a spammy content and penalized your website.
This tag is more similar to the 301 redirect as this redirect code permanently redirects a page from one place to another. Though, there are few main different between these two:
•    301 Redirect is the way to redirect all the traffic of your website as well as spiders or bots, while the canonical tag is just for the search engine bots.
•    301 redirects carry the functionality of cross domain means you can redirect a webpage from one domain to another domain and also carry all those metrics of search engines while Canonical tags works on a single root domain.
By implementing rel=”canonical” tags for each page of your website and specifying the correct URL you want to signify each page of your content, you will go a long manner in preventing the most common variants of duplicate content, and by expansion, give yourself the best chance for exceptional search engine rankings.
