Yesterday I came to know that using full URL instead of just page name helps in
SEO.
For example if you have a site
www.example.com and you want to place a link of Contact Us page on home page then it should be done like this:
<a href="http://www.example.com/contact.htm">Contact Us</a>
instead of doing this:
<a href="contact.htm">Contact Us</a>
Don't know if it is true or not I am trying to find this out.
