I see some sites where every link to another page within the site is an absolute one i.e. on www.madeupname.com there is a link to the sitemap which is http://www.madeupname.com/sitemap.htm rather than just sitemap.htm or /sitemap.htm
What are the disadvantages or advantages of this. Surely if you have a keyword in your domain name and then lots of absolute internal links you might get penalised for over use of the keyword??
Comments much appreciated
