The site I do a lot of work for, , has three ways of getting to the content: , , and .
= PR7
= PR6
= PR6
Keep in mind, all of those URLs are the exact same website. Would it be beneficial to get rid of ? I'm just fearing that becase we have so many urls, links to our site is spread out over different base URLs, and Google thinks that and are different sites (and thus giving them different PR ratings).
Any comments?
