do links from Myspace profiles or blogs with PR4-5 value same as PR4-5 web site ? i meant would they help for a PR increace ? also links from non english site to a english site has the same value as a english site ? .
It depends on what you're talking about as far as "does it help?" English to non English - still provides backlinks, and depending on the site, perhaps it has an english version where you just have to click "english" or translate in the top corner or something... If that's the case then yes, because it would also be indexed in the English version...
IMO PR5 myspace or blog is the same with other PR5 websites...it is good if there were relevant and of quality if you will link to them...
