Every page have URL, it show estimated info about submitted pages. Example, it have google, yahoo, digg and many unknown url's. In each page there is for example digg.com and www.digg.com, digg.com direct to my domain..com/digg.com and the www.digg.com without any hyper link, should I put "NOFOLLOW" ?
if you dont have links in hyper links, then where you will need to use nofollow. but if you make hyper links, you should add nofolow tag to links.
if.... there is no if come on mate.go back to your office and making your money,dont make these if dreams.
