URL / Domain Canonicalization for Dubplicate Content Removal

No Comments

Duplicate content in search engine database like Google is strongly prohibited. Website that evolve with both domain calling protocols of www. and without www create two similar contents each time the search engine bots visit the website to index pages. This force search engine to abandons indexing pages with duplicate contents.

The two domain calling protocols are

Assume my domain name is “mydomain.com”

My website will evolve in two URLS

  1. http://www.mydomain.com
  2. http://mydomain.com

When I put content to the website, each page I create will propagate as two URL


If I create a page for Domain Registration it will create two URL like shown below:

  1. http://www.mydomain.com/domain-registration.html
  2. http://mydomain.com/domain-registration.html

To avoid this just allow one protocol to be used during page calling by the browser. To achieve this you must redirect one protocol to the other.

let say I want to use only www.mydomain.com
