Domains with www. and without www

The search engines like Google , Yahoo , Bing , and others, do not like that there is content duplicated on the web, for example, is very common that a given domain has two inputs, with www and without www at the beginning ( www . dominio.com and dominio.com ). This can present problems for our site because if you Google our Pagerank , rather thanincrease , may be affected . To avoid duplication of pages registered, we will have to make a decision.

There are several ways to force the system to using a 301 redirect , our domination takes one of two forms . For those working on a server Apache and therefore have the ability to create and edit a file . htaccess in the root of your server, you can choose to add one of the following codes:

If we want all accesses are redirected to a domain with www, we add:

RewriteEngine On
HTTPHOST RewriteCond% {}! ^ Www.
RewriteRule ^ (. *) $ Http://www.% {HTTPHOST} / $ 1 [R = 301, L]

If our intention is to remove the prefix www to our access, this is the code:

RewriteEngine On
RewriteCond% {HTTP_HOST} ^ www. (.) $
RewriteRule ^ (.) $ Http://% 1 / $ 1 [R = 301, L]

The choice is yours. You must choose one of the two.
