URL Canonical Issues

A website can be accessed in many ways.






If a search engine gets more than once references/links etc from your internal pages or from external links then it may think that these websites are different and it may cause a lot of problems including most notorious Content Duplication.

How to find out if you have URL Canonicalization issue?

Type site:http://yourdomain.com and site:http://www.yourdomain.com and check if you get different sets of results which include both or more instances? If answer is yes then you are in trouble.

How to avoid URL Canonicalization?

Simple, always use one form of URL for website whenever you have to link it either internally or externally.

I personally prefer http://www.domain.com to avoid any clash with http://domain.com.

Ain’t both domains same?

No both are not same.

The actual domain is http://domain.com

www is one of subdomain of http://domain.com.

You can have as many subdomains as you want. Ex. http://blog.domain.com, http://news.domain.com and so on.

You must avoid URL Canonicalization at any cost and it must be included in your SEO to do lists. Without it you might find hard to get into Google top 10 ranking.
