Boy does this open a complete topic of "link popularity games"
Is there a "no index, no follow, etc" in the header of the link page you are buying?
Is the page blocked in the Robots.txt file?
Is the link on a cloaked page?
I did major link popularity programs for our clients (~7,500) and it was not worth the time or effort. And I will not even discuss the money. But I never considered buying a link. If Google or the other SE find out, the site is penalized and you are out your money.
I would take $29 US of it and go to a site like LinkMarket .com and start to meet other sites that want to link as well. They all will play games but you will also find really great sites (webmasters).
Remember in the Link Popularity game, a PR0 site is either new or banned. Therefore check the age of the site. If it turns out to be new, link to it. When Google indexes it and it goes thru the first two PRs, you might luck out a get a PR 5 site.
But to buy a PR 6,7,8,9. These are the Pro Game players and you will never see the PR transfer to your site.
Save your money.
And you never know, you may be talking to someone who also needs links. So always ask:
Would you link to my site?
And I would say yes. And my clients would also. They just want quality, no games sites that will be there this time next year.
