A recent post on Digital Point prompted me to write this short article on how to estimate the number and strength of links required for a given PageRank:
How can i get better page rank of my website. How should I put links in my website to get better page rank. Kindly suggest?
PageRank is determined by the quantity and quality of the links to your website. As a vaguely general rule each Rank is at least 10x harder to reach (and also 10 more valuable) than the one below.
For example, it generally takes at least 10 PR 3 links to equate to the value of one PR 4, sometimes more. Further, each of those PR 3s is on average worth at least 10 PR 2 links.
Please note that PageRank isn’t the same as the actual search engine rankings. Even a PageRank 10 site such as http://www.adobe.com/ will only rank well for relevant (in Google’s eye’s) phrases.
As such, a high PR alone is no guarantee of a ranking well for any given keyword, the site also has to be optimised for it, and ideally the link’s to it should have relevant keyword in their anchor text.
As a general rule, a pages PageRank is equal to or a level below its top tier of links.
So, for example, a site with say:
5 x PR5 links
22 x PR 4 links
44 x PR 3 links
100 x PR 2 links
350 x PR 1 links
950 x PR 0 links
1000 x unranked links
Would probably be a PR 4 site, bordering on PR 5. Adding a few PR 6 links, plus a few more PR 5s would probably bring the site up to a PR of 5.
On the other hand, it would probably take over a dozen PR 5 links to bring the page up to PR with any from PR 6 pages, but even hundreds of links PR 4 links, or thousands of links from PR 0-3 sites might make no difference.
This is because as per my earlier rule of thumb, all other things being equal, each PR 6 link is worth approximately as much as around 100 PR 4s.
