More about Page Rank

[rcaponeg]

A couple of you guys said you don't care about Page rank. I thought you needed a good page rank to get listed on the first page of the search engines? If you have a low page rank how do you generate alot of traffic? Thanks for the help Frank

Frank, you posted this question in your earlier thread here. This is what I posted there before I saw you'd started this new thread:

I thought you needed a good page rank to get listed on the first page of the search engines?

I mentioned in an earlier post in this thread that you're probably only looking at only one of at least three PageRank calculation results.

There is Toolbar PR, which is pretty easy to see but only shows a kind of historical PR which may be three or more months out of date and isn't what Google actually uses to rank your page.

Then there's Directory PR, which you can see if you have a site listed in the Google Directory (though you need to know how to translate the visual green bar graphics into numbers*).

And then there's Real PageRank, which you can't see and mostly can't calculate for yourself. This is the one only known to Google itself and this contains the real-time values that make up part of the ranking systems that determine where your site may appear on certain search results today.

Take a look at the math examples on the Wikipedia PageRank page and if every bit of it makes perfect sense to you, then it might be worth spending a little time trying to understand how Google may be calculating things at the moment, though you'd have to run many thousands of well-defined tests on your own pages and sites to build your own data sets. And just when you have it all figured out, Google is likely to change their algorithms in ways that will invalidate your results.

On the other hand, you can just concentrate on the things you can really do that will help, like my suggestions in that earlier post here.

* The Google Toolbar Pagerank is a 11 unit scale of 0-10. The Google Directory Pagerank scale is a 8 unit scale. The 8 units can only been see by looking at the code that makes up the Pagerank green bar. The 8 positions are cleardot.gif, 5/35, 11/29, 16/24, 22/18, 27/13, 32/8, and 38/2 (pos.gif/neg.gif).

How PR influence the result is a great mistery, people can only guess The one thing is right, IMHO, that PR is just a mathematical prediction of probability that surfer will appear on the page, nothing more. Read the theory of Markov chains, you'll find lots of things that really reflect all the web. Google's algoritm of assigning relevancy is very difficult, and it take account of PR, but it is not even 50%. The top position by the word "porn" you'll have, if the googlebot will appear on your site by the link "porn" and find the word "porn" the most relevant on the page(how - it is another speech). I think you need aproximately 10^6 - 10^9 backlinks "porn" on your site to be surely the first in google by the word porn
