The Google Pagerank Algorithm and How It Works

Faglork · #1 (**permalink**) 03-02-2005, 05:21 AM

Just found a very nice article and thought I'd share it with you:

"Page Rank is a topic much discussed by Search Engine Optimisation (SEO) experts. At the heart of PageRank is a mathematical formula that seems scary to look at but is actually fairly simple to understand."

Indeed - the article offers an excellent insight.

Google is gone way beyond pagerank.. try and anwser me why the SERPs are jumping from current listings, to last weeks listing to last months listings, all within one day and then I will be impressed. It all depends on what time of the day it is.

My page was rotating from #2, #4, and #6 all week long in this pattern (for reasons unknown). Now it appears to list exactly where it did last month (and all new listings from other new sites have disappeared from the ranks altogether).

Why aren't more people talking about how Google is acting?

I've noticed that if you do a search for a term, it will display results
Results 1 - 10 of about 11,500,000
if you do the exact same search in a few minutes, few days, etc. it will display
Results 1 - 10 of about 11,670,000

Because Google searched 120,000 more searches the second time, the SERP's will be slightly different. That could be why the results of your site are bouncing from #2 to #4, etc.

Next time you do a search print out the page and keep an eye on how many sites Google (or any other engine) is searching.

I read on another authorative forum the PageRank has nothing to do with SERPs - actual placement and ranking.

I have a PR6 site (because it has about 2000 inbound links) but if I link that site to another with only that one link it gives the other site a PR of 4...

Mafamatics - pah!

This thread has cetainly wandered off.

There are definately two significantly different google serps coming back on my searches. One big and one small.
one 550K > other 480K
one 2.2 Mil > other 650K

If you get SERPS 1 or 2 has been the time of day, seems to shift in the afternoon and has been steady at night and late nights.

There is a major difference between the two, but the smaller does not respect backlinks or PR very much and vaults alot of BS PR0 sites to the top.

On topic though, a good article i only wonder if the time in implementing a suggested change is worth while when PR seems almost lost in the ranking system.

I think that in this case is envolved some 'link age' factor. I've got pages in my directory that are created 4 months ago. They are linked from exactly the same places as the old pages end even have less OBLs, but they show PR2 and the old ones are PR3. Go figure it. :)
