For example, if your site's current PR is PR3, its current weight is 125, so to make it PR4 you need to buy a link (or links), which will pass to your site at least 500 more weight. Then its total weight will become 625, which will increase your site PR in the next Google PR Update to PR4. Learn more about Passed PR Weight.
Note: if your site is PR0, and it has no PR0-PR1 links, purchase at least ~300 PR0-PR1 links for it before you start to purchase higher PR links (this is necessary in order your link popularity campaign looked natural to Google). Directory submission service is one of the cheapest ways of getting many PR0-PR1 links. If you want to get 300 links from directories, you need to purchase at least 3,000 submissions (from our experience we know, that most directories won't add your link or will remove it with time or it wouldn't even be found by Google on their site; this is why you need around 3000 submissions to get 300 links).
Note: if your site is PR0, and it has from 300 to 500 PR0-PR1 links, don't buy PR4+ links for your site at once since it may look unnatural to Google. At first purchase several PR1-PR3 links. A week or two later purchase a few more PR2-PR3 links. A week or two later purchase a few more PR3-PR4 links. A few more weeks later purchase a few more PR3-PR4 links. And only then you can slowly start to purchase PR5 links for it. And even later - PR6 links.
