Buy a link from a PR9 site? I don't know why you're worried about PR for, it's not a major factor in rankings.
^^ amen ... The PR misconception is the most prevalent in the SE illiterate Webmaster group! It sucks when people mail me and say that they pay me 250$ if i get them PR4 or 5 or as in this case 7! @ visible_anupam2010 Bro, PRs are not everything when doing a site optimisation! Nor will they get you any kind of traffic! For an example .. my site www.xabhishekx.com has a PR 5 and is not optimised for any keyword ... has no pages indexed and has no backlinks too! But still it's Pr5 !! That way .. I just wanna say that PRs actually mean nothing, they are just a way of google to determine the importance of a page, but they donot in anyways hel you gain SE traffic! If you get what I am saying! Cheers, Abhishek
if you want a pr7 start link building and keep link building, pr does not matter focus on getting good serps and the pr will follow
You can get a spike in your PR by buying a lot of links. However, if those links aren't from relevant sites or have little quality, your PR will come down as fast as it goes up. I agree with focusing on good valuable contents, targeted keyword rankings, conversation. These are what ultimately bring business.
Whats funny about "seo optimization" is that it is a commonly searched for phrase with little competition. I talked about it on my blog in order to capture some of that traffic here: SEO optimization
