Google PageRank Formula


0.15 + 0.85 x ( a share of the PR of every webpage that links to it) = Your Webpage PR

0.15 = The lowest PR a webpage could ever possibly have.

0.85 = A dampening factor... This is just the number that Google uses for their PR formula.

"share" = the PR of the page linking to you divided by the total number of links on that page.


Say we've created our website and it has 3 pages in total. For sake of making the math easy,
we'll start each webpage with a page rank of 1.
  • Page A
  • Page B
  • Page C

None of the pages link to each other. They're just pure content webpages with no links to any
other pages within our website. Let's quickly calculate the PR of our pages by using the formula

0.15 + (0.85 x 0 ) = .15

Because no webpages link to our pages, there is no "share of PR"... hence it is 0.
So... If we do the math, we come up with a PR of .15 for each of our pages.

Now, let's see what happens if we link page A to page B.

Using our formula we get:

  • Page A : 0.15 + (.85 x 0) = .15
  • Page B : 0.15 + (.85 x 1/1) = 1
  • Page C : 0.15 + (.85 x 0) = .15
You can see that by just linking page A to page B, we've changed the PR of page B from .15
all the way up to 1. Big difference!
With our newly calculated Page Ranks for all of our pages, let's do the calculation again. By
doing so, we'll slowly get to the "true page rank" of all of our pages... The more iterations we
do, the more gradual the change will be between each iteration.

  • Page A : 0.15 + (.85 x 0) = .15
  • Page B : 0.15 + (.85 x .15/1) = .2775
  • Page C : 0.15 + (.85 x 0) = .15
You can see that after another iteration of our formula, the PR of page B dropped
significantly... This number is closer to the actual Page Rank that Google would give page B.

Now, let's try something different and link all pages to and from one another...

  • Page A : 0.15 + (.85 x 1/2) = 5.75
  • Page B : 0.15 + (.85 x 1/2) = 5.75
  • Page C : 0.15 + (.85 x 1/2) = 5.75
After 1 iteration the Page Rank of all pages is .575.
So, by linking ALL pages together we have maximized the page rank from within our website!
You can play around with your linking throughout your website and by doing so, you can send
more PR to pages you want to rank higher for, and lowering the PR of those pages you don't
care much about their ranking :-)
This can be extremely powerful.

Google PageRank Update

Google PageRank has been updated these days and my Vista site is now PR5 ! Some of the data center show PR0 yet but I think they will update soon. My forex site is still PR3 but I dont work on it lately.

Average Visitors of my Vista site increases to 300

I am happy thats happening, but I see decrease of AdSense earnings and maybe I need some design corrections and new ads position. I will start experimenting with positions and colors of my ads. Hope it will improve.

I have a lot of work to do on my oldest project: Its currently PR3 but theres not much traffic - only 5-10 uniques a day. I need to:

  • Optimize it
  • Add more articles
  • Get more backling (I am working on that)
  • Clear my forum spam and get better captcha protection
Lots of work for a lazy person like me :).
Thats it for now.

Projects I work on

Lately I've been working on SEO & Marketing on some of my sites. So far I have participated in DigitalPoint forum which is good source of useful information and resources on that topic. This forum helped me much but I am not fully satisfied with my achievements. I need more quality backlinks to my sites and more attention-grabbing content.
So far one of my sites averages 150-200 unique visitors per day, generating little adsense revenue (1-2 bucks a day). This is my most visited site. Most of the traffic is organic from google search queries which is great, also I am well-ranked for some popular keywords. I need to work toward next level and target 500 visitors a day for this site.

Current: 200 visitors/day
Target: 500 visitors/day

My plan is to:

  • add more quality articles with good keywords
  • post regularly to social bookmarking networks
  • generate backlinks from good PR domains
  • be patient and wait for the target to happen

Thats what I am concentrating on lately. This is my main project and I keep working on it.

Welcome to my blog

Hey, Thats my first personal blog. I am planning to post here my current projects and share knowledge on these topics:

  • FOREX Market Trading
  • WEB SEO & Marketing
  • Templates & Graphics Design
  • C / PHP Programming
I hope you enjoy it.
