A
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
above.
+
* = .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. Not very good huh?
0.15
(0.85 )
0
(PR 1)
B
(PR 1)
C
(PR 1)
Page Rank formula:
+ *
=
Your Webpage's PR
Now, let's look at a quick example.
0.15
0.15 = The lowest PR a webpage could ever possibly have.
(0.85
)
0.85 = A dampening factor... This is just the number that Google uses for their PR formula. 1
(a "share" of the PR of every webpage that links to it)
"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.
