I have on my sites and blogs : 1 PR -5 Page ( Blog homepage) 3-PR-3 Pages Dose these help Increase my traffic ? Also my pages are getting +1 PR almost one mont . What Does This Mean ?
You're probably not going to get much trying to sell links unless you're getting some decent traffic. PR is useful for trading links and such (which even in themselves are of debatable usefulness) but you're probably going to need higher than a 5 to impress someone. I had a PR3 just a couple months into making my site. Higher PR values are harder to obtain but I'd definitely recommend against paying cash just for a single link, especially when if you're making good content you can ASK for FREE links from reputable sites in your field if you have something to offer. It's worked for me time and time again and if someone has something good to mention to me that is relevant to my site I don't hesitate to link to them.
Then why do people Buy the Links On Higher PR Pages and even why theree will be a lot of discussion on Directory? Then Why should People Buy The links form The Directory by Paying them ?
