Google Algorithm for PageRank

The Google PageRank algorithm

PR (A) = (1-d) +d (PR(t1)/C(t1) + … + PR(tn) /C (TN))

4little1s.com is a baby gift and nursery furniture website located at http://www.4little1s.com/ and has recently started up this year. In an effort to gain a better understanding of getting onto the first page of Google for marketing purposes, PageRank appears to be one of the keys to this process.

While appearing not to be a totally exclusive factor, having a good page rank appears to help your position within Google. I say ‘appears’ as the overall algorithm to a high position does change, so while one day the emphasises is on xyz, it may and probably does change, once people suddenly realise what they should be doing. DMOZ being a good example of this!

As a mathematician by trade, starting the business was excellent for my brain, but when we talk about Algorithms its heaven.

The equation above is actually quite easy to understand and I try to explain as simply as I can:

PR is the actual Page Rank you are looking to get
A = The Web page in question (use your home page as an example)
d = A suppressive dampening effect variable I suggest a value of 0.85 is not far from the mark
t1…tn = Pages linking to (A) In this case we used our homepage
C = Is the number of links on the page that are outbound to other sites you have linked to
