Recently , I found this pagerank method .

• i have a few backlinks from a lowpagerank site (pagerank 0 and 1)

I found my pagerank as low when checking . Really a shocking one .

• According to wikipedia definition , Pagerank depends how it is connected with other sites not with traffic.

I need your replies to confrm my message .

Yes pagerank is all about the following;

number of backlinks to your site;
are the backlinks dofollow;
do those backlinks have any PR value;
does the backlink page have way to many other links (over 20 would be alot when wondering about PR).

In summary I had a PR3 site that only had one PR4 link pointing to it. Quality over quantity if you can find it. Also the link was well aged and I think the big G places some value in the age of the backlink.

Every page in a site will start with a Page Rank of 0.15. And the PR of the page will be increased by having more higher PR sites that link to it (inbound links).

There is even a formula for Page Rank :
PageRank = 0.15 + 0.85 * (a portion of the PageRank of every page that links to it).

A portion is defined as the linking site page's PR divided by the number of outbound links on that site.

If you are going to post "facts" please make sure they are correct first

We assume page A has pages T1...Tn which point to it (i.e., are citations). The parameter d is a damping factor which can be set between 0 and 1. We usually set d to 0.85. There are more details about d in the next section. Also C(A) is defined as the number of links going out of page A. The PageRank of a page A is given as follows:

PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))

Note that the PageRanks form a probability distribution over web pages, so the sum of all web pages' PageRanks will be one.

Well yes, traffic and PR are not necessarily related. PR follows an algorithm and not all backlinks will necessarily pass on PR due to the rel="nofollow" tag.

just cos you seen something on wiki does not make it true, wiki is widely known for bias in 1 direction or another and is subjected to malicious edits almost every second. that being said i would like to point out the 1 underlying fact which is - NOBODY knows how pagerank works except the technicians at google, everything else is pure speculation. I have had sites with no links to them and a few pages of unique content get PR4 after a few weeks and then seen sites that have got 10,000 manual on content backlinks only get PR3 after 2 years.

pagerank is only usefull if your a link seller - IMO
