Why doesn’t Google rank itself 10 out of 10?

Today Sam Oakely and I were having a little chuckle in the office at Google’s page ranking system. You can have it as part of your browser if you have the Google toolbar.

It’s a pretty useful tool which gives you a ranking out of 10 for each blog/web page. This can be a useful guideline as a starter and the criteria changes regularly resulting in the less important sites being down graded etc. Currently, this blog is 4/10 which isn’t bad but isn’t great – note to self must work harder!

Wikipedia describes the page ranking system as follows: PageRank is a link analysis algorithm that assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of “measuring” its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references. The numerical weight that it assigns to any given element E is also called the PageRank of E and denoted by PR(E).”

However, today when Sam and I inspected Google itself we realised it only had a ranking of eight out of ten. How the hell do you get ten out of ten and why aren’t Google achieving that? Surely they rank themselves pretty highly – also I am interested to know which sites do get 10.

I know Netvibes only manages nine which is pretty good but lots of people use that site. If you know how to get a 10 feel free to post your comments as I am genuinely interested.

  1. Thanks Simon, well when I look at Google.co.uk and it ranks as 8 on my system and the others in the office have found the same thing this is quite puzzling.
    I thought it might be a .co.uk/.com thing.
