hi guys..i have a website with pr 8...i have about 15 link pages all havin the exact same content..the content is just links of various people on all those 15 pages...i was wondering if google penalises for this...also, by placing a link on these 15 sites, with pr 6 all of the same domain, will it help as far as link popularity is concerned? or will it just be considered as 1 link since all 15 links are coming from the same domain.....
