Google PageRank Table - Compare Pagerank Values

PageRank Values

Although nobody knows the exact Google PageRank values the table below gives a fairly good representation of how many external links, of certain PageRank values, are required to achieve a certain Google PageRank.

For example, if you want to know how many incoming PR4 links that are required to achieve a PR4 for your site, you simply look down the Page rank 4 column, until you come to the PR4 row and the answer is 18.5.

So you need 18.5 PR4 links to achieve a PageRank 4 for your site? Not quite.

This is certainly the case, if all of the incoming links are from PR4 pages with less than 50 external links and the links are on-focus with your content, but the value of the PR4 link is reduced if there are more than 50 links on the page and the page topic is not on focus with your site. As a guideline, however, the table gives a good indication of what you should be aiming at.

PageRank Calculation

 
PR   Links Links Links Links Links Links
    For PR3 For PR4 for PR5 for PR6 for PR7 for PR8
 
1   555 3,055 16,803 92,414 508,277 2,795,522
2   101 555 3,055 16,803 92,414 508,277
3   18.5 101 555 3,055 16,803 92,414
4   3.5 18.5 101 555 3,055 16,803
5   1 3.5 18.5 101 555 3,055
6   0.5 1 3.5 18.5 101 555
7   0.5 0.5 1 3.5 18.5 101
8   0.5 0.5 0.5 1 3.5 18.5
9   0.5 0.5 0.5 0.5 1 3.5
10   0.5 0.5 0.5 0.5 0.5 1

Compare PR Values

Moving one step further, we are often asked what a PR4 link is worth, or a PR5 link is worth compared to a PR3 link, for example, so to try and make this easy to understand, we have listed the PR3 equivalents below.

PR2 =
0.2
of a PR3
PR3 =
1
of a PR3
PR4 =
5 x
PR3
PR5 =
25 x
PR3
PR6 =
125 x
PR3
PR7 =
625 x
PR3

So, as you can see above, a PR6 link is comparative in value, to 125 PR3 links, so it seems fairly obvious that your time is better spent in trying to achieve a few quality links rather than bundles of lesser quality links. We have used the example of PR3 links, there is an assumption in the industry that if a link does not appear on a page of at least PR3, it is not worth having.

We would say that since Update Jagger, it is worth considering a link from a web page of PageRank Two or above, as long as it is:

  • On focus with your product or service
  • The website’s index page has a PR of 4 or above
  • There are less than 50 links on the page
  • There are no undesirable external links on the page
  • There are no nofollow tags on the links
  • There is no robots metatag on the page with the content,” noindex, nofollow”
  • There is no javascript redirect on the link
  • The link is not redirected

Link Campaigning

Although link campaigning is a laborious and time-consuming task, every website owner should be running an ongoing link campaign, either themselves or through a search engine optimisation professional. Look to add the equivalent of 30 PR3s to your site each month, preferably made up of higher PageRank links, i.e. 6 x PR4s or a PR 5 and 5 PR3s. Don’t go crazy and try and bring in hundreds of links in one month, keep the progression as natural as possible.
