My main site www.woodenflooringsales.com which has many thousands of pages has a pr on most of the site of 3 and some parts 2, but a site a built www.woodenflooringsales.co.uk which is a doorway site has pr4 and i don't know why, can anyone tell me why. I have built a new site with batter navigation and looks better I'm not sure if i should leave it on the domain it is on www.woodenfloorsales.co.uk which is an old domain which has never been used or put this page up as a 2nd index page on www.woodenflooringsales.co.uk/index.php which has a pr of 4, I'm adding a RSS feed to the page, I'm not sure if this will help the site, or if i should try with the old domain which has no pr value.
