I think it will affect your website not improve.

any answers?

It most likely will do nothing. Im sure the site has some "real" backlinks to it but prolly nothing of any value.

yes but i saw that the pr6 website have also a blogroll link with another website and that website receive dofollow backlinks for it.
and also it is same niche like me.
i think it couldn't affect my website and also is just 11$..

What exactly are you planning on doing with the site?

You need to investigate the backlinks. Any ranking power that can be pulled from the site will be a direct correlation to the number of quality backlinks that exist pointing to it.

If it is nothing, but PR 0 and PR n/a links, there really is no point in buying it.

mike check you pm please.

I will not buy it. I would rather buy a real PR 1 or 2 for that amount. Atleast I am sure that it is REAL.
