Andrew Antaro asked:
HOW MANY EXTERNAL LINKS DO I NEED?Soon after publishing my ”A Beginner's Introduction to the Google Pagerank” article at the ArticlesBase, many intrigued people sent me an email to ask, “How many links are required to get a particular Google PageRank?” This follow-up article will answer this popular and important Search Engine Optimization question.
GOOGLE PAGERANK RESEARCHTo get accurate research, I decided to pick an industry and get the Google PageRank (PR) and number of non-duplicated Inbound Links from a random sample of fifty websites in that market. A month after the New Year's Eve celebration, I found myself pretty quite, so I picked popular beverages, mostly focusing on energy drinks, sports drinks, and soft drinks.
All the data below was collected during the first week of January 2009. This was an optimal time for this information because Google updated every site's PageRank within the past week. All data is sorted in descending order, first, by PageRank, then, by Inbound Links.

DATA CONSISTENCIES AND DISCREPANCIES
On the whole, the Google PageRank to Inbound Links relationship is quite consistent, and we can draw definite conclusions about how many links are needed for a particular PageRank. There are some noteworthy variances, however, as two sites both have 42 External Links, yet one has a good PR4 while the other a poor PR2.
As explained in my previously published PageRank article at the ArticlesBase, Google does not value all Inbound Links equally. The two main factors Google uses to assess the value of an External Link are:
(1) The PageRank of the site linking to you (the higher the PR, the great its value);
(2) The similarity between the keywords of the site linking to you and your site's keywords (the higher the "Relevance," the greater its value);
These two factors account for most of the divergences between quantity of External Links and resulting PageRank.
WHAT RESULTS CAN YOU REASONABLY EXPECT?
You will require less QUANTITY of External Links to earn particular Google PageRank if they are a higher QUALITY, and vice-versa. That being stated, these are the results you can "reasonably" expect:
PR 01 requires 10 Inbound Links
PR 02 requires 25 Inbound Links
PR 03 requires 50 Inbound Links
PR 04 requires 100 Inbound Links
PR 05 requires 200 Inbound Links
PR 06 requires 400 Inbound Links
PR 07 requires 800 Inbound Links
PR 08 requires 1600 Inbound Links
PR 09 requires 3200 Inbound Links
I hope these guidelines help you set and reach your SEO goals. Best of luck with your link-building campaign and with increasing your website's Google PageRank and total traffic!
