When submitting your site to a directory, whats the best way: http://domain.com, http://www.domain.com, www.domain.com or domain.com ???
it does matter...the search engines treat them as links pointing to differenct pages...ever heard of url canonicalization?
It is best to always use www.domain.com because this is what the majority of web users expect and type, even if you do not use it. The reason for sticking with one version is to avoid canonicalization problems. Hint: Use your .htaccess file to redirect all non-www visitors to your www document addresses. Background: The non-www version is technically correct because it is redundant to http://, which itself indicates a web address as opposed to an FTP, Telnet, IRC or other method of Internet communication. While technically correct it is not the best practice because the use of www is overwhelmingly popular. This is a case where it is best to go with the flow.
Most directories I've seen want that http://. I believe this is because the link could otherwise appear as http://www.directoryname.com/www.yoursite.com. I know those times when I've accidentally left the http:// off a link to another site on my site, that is what happened. I'm sure some directories can handle either, but why risk it?
Many directories do require you to type http:// before the actual domain name while submitting, so I think you should stick to http://www.domain.com.
do a variation between http://www.realhousing.info / http://realhousing.info and http://www.realhousing.info/index.php
have you been reading the thread?.....didn't we already address the problem with url Canonicalization?
I would also add RewriteEngine On Options +FollowSymlinks RewriteBase / RewriteCond %{HTTP_HOST} ^yoursite\.com [NC] RewriteRule ^(.*)$ http://www.yoursite.com/$1 [L,R=301] Code (markup): in your .htaccess this way yoursite.com will be permanently redirected to http://www.yoursite.com Google will love you for it
