I am really not getting the page rank algo.

If I have a menu on the site that points/links to every page on the site doesn't that give me great page rank for all pages in the site?

example 4 page site using http://www.fastforwardmarcom.com/default.asp

Pages
default.asp
network.asp
programming.asp
exchange.asp

if default.asp points to network,programming,exchange and default.asp what does this do for page range?

if network.asp points to network,programming,exchange and default.asp
what does this do for page range?

if programming.asp points to network,programming,exchange and default.asp
what does this do for page range?

if exchange.asp points to network,programming,exchange and default.asp
what does this do for page range?

Is this an index heavy page rank or my own crazy idea of page rank.

Please help. lossing my mind.

Scott, I will try to simplify the algo:

Everypage has a discrete variable weight 9 points, 1000 points whatever the #'s arent important.

Now each page once it has recieved those weight points will NEVER lose them, what the algorithm allows is for that page to give away 85% of its weight points while still keeping 100% of its weight points.

An example is if I have a page with 100 weight points and I have only 1 link off of it to only 1 page then the end result is my original page still has 100 weight points and my page that I linked to now has 85 thus the "systems" PR has increased to 185 weight points even though we only had an injection of 100. You can easily verify this over at Phil C's pagerank calculator http://www.webworkshop.net/pagerank_calculator.php3

Now for the cool part: seeing as we linked page b from page A page B now has 85 points and if it reciprocates it passes 85% of its 85 points back to page A so it keeps its 85 and gives back 72.25. So now the main page in a round about way used its own 100 points to give itsself 72.25 more and it has a total of 100+72.25= 172.25

And guess what Page A still links to page b so instead of now giving 85% of 100 points its now able to give 85% of 172 while still keeping its 172 so you see how this reciprocation loop within your own site can be used to augment your pagerank once you get it

Now for more then 1 page it works the same way as the example above you just thave to divide the 85% by how many links (Both outbound and inbound) that are on the page.

Lets say you have 2 internal pages and the same original 100 weight points. Link to both of them and you donate 85/2 to each page and then if they reciprocate 85/2*.85 back and so on

I think you should really give Phils page a read as it covers a lot about the algo that i could duplicate here but heading over there gives you the luxury of playing with the PR calculator

If you have any questions and want to discuss this real time I'm always on msn at seoguy@seo-guy.com or you can give me a call 250-751-2447

If for example you have a text menu on all pages...
On some pages you use breadcrumbs or just a longer text link to point to a page as your text menu does.
So... the page has lets say, 11 links of which 2 are the same page, one from the menu and one from the link of the page copy.
Transfer would be (PR/links)*.85
I guess you see it coming now... will transfer be (PR/11) or (PR/10) ?
Google will pass PR only to one of the 2 same links, but will it devide it still by the total of links ?
If it used 11 and passes only 1/11 of the 10 links then some PR is lost.
