PageRank is not important?

During these Google dances, we found PR has got some changes different from before. Somebody said that PR is getting less important, it's just a sign to evaluate our website if it's trustful. It's totally different from SERP, also not affects SERP of your site.

I think PageRank is not becoming less important, but more important, just evaluate a different aspect, compared with SERP. The old PageRank system includes only one sign to evaluate the quality of a webpage, that's unilateral and easy to be abused by someone.

A good webpage evaluating system should have more than one aspect to be considered. So, I think Google is starting to use a new arithmetic to calculatie PageRank, together with SERP, they are both the important factors to evaluate a webpage. It's more fair than before.

SEO professional should take care both sides to optimize their own websites, that's more difficult than before. That means a webpage which has good PR and SERP is the best.

Myth of Google PageRank Prediction

Are you believe those pagerank predictions tools? Here is a software developer's explain for it. Maybe you can estimate it by yourself.

Pagerank predictions tools can't really predicting pageranks, they can't even guess or get your next pagerank. They are all based on a "urban legend" a myth in other words.

If you give a special query to google toolbars, it will report you the first 15 best incoming links for a website! Only the first 15 , if you got 3000 backlinks, only the best 15. Please note that the best 15 don't mean the first 15 with the higher PageRank. The top backlinks are also calculated on how many outgoing links, the websites topic related to your website topic,etc...

This scripts, are just grabling those 15 results, and they make a media like this:

(n1+n2+....nX)/X - X is total amount of 15 results.

EX :
(PR1+PR4+PR4)/3

or
(PR1+PR4+PR4+PR1+PR4+PR0+PR1+PR4+PR9+PR1+PR4+PR1+PR2+PR2+PR4)/15

Now do you get why iwebtools and others websites are writing things like this "Your next predicted PageRank is 6.5" or "6.54" do you get it now, from there the decimal is coming from?!

Let's show you some very well known problems.

1. it only reports the first 15 backlinks. If you got 4000 backlinks, and all of them are PR3/PR4 it won't show more then a PR4...and I more then sure that with 4000 backlinks of PR3/PR4 you will get more then a PR4.. because only the first 15 counts... and they only do an "aritmetic media"

2. If you only get a single PR6 backlink it will calculated

(n1)/1 = 6 / 1 = PR6 ... that isn't bullshit?!

for 2 PR6...
(6 + 6) / 2 = PR6

for 3 PR5s...
( 5 + 5 + 5 ) / 3 = PR5

3. Some scripts are even more crayz. they don't divide by "n" ... they think that all websites are having more then 15 backlinks, so they directly devide by 15... So if you buy a PR8 backlink,and that is your only backlink, then your predicted pagerank will be:

8 / 15 = 0.5 it will be rounted to 1 !

Google: update at 2006-07-13

July 13's google update made some site's PR changed and BL updated, most of sites have nothing happened. Compare with Apr's big update, I think this update just Google's little adjustment. Apr's update made many new websites got high PR, this time Google let them turned back, Google's pageRank cheking is becoming more exact.

Obviously this update is not a whole PR update, I bieleve a new big dance will come at the next several months.
