Managing www.xxx.com and xxx.com – Domain name Vs the Universal Sub Domain

Domain name Vs Universal Subdomain

Last week one of my friend was asking me about managing www.xxx.com and xxx.com,  Few days back one of my blog follower raised the same question through chat, so i felt like answering the question through this blog post.

For eg: xxx.com is the domain name and www.xxx.com is the Universal subdomain for xxx.com. www was used by domains to connect the domian name to the world wide internet sphere. Now with the advancements in internet technologies www is not required. But as a practice we still us the domain name as well as the universal subdomain. So it is clear that for every website we create we obviously get two URLs generated (xxx and www.xxx).

Search Engines treat www.xxx.com and xxx.com as two different indiviual websites mostly with the same content. Usually Search Engines treat these two URLs with same content as duplicate content and it is not advisable too. So i its always good to redirect www.xxx.com to xxx.com because xxx.com will be helpful in building Sub domian architecture ie., we can build the site as news.xxx.com or movies.xxx.com
