I found this article and think it is very useful.Enjoy

I am sure Googlers should be enjoying this: hardly can they say a word, there follows a wealth of guessed and speculations. This time Matt Cutts is said to have mentioned that their 200 variables in Google algorithm and already plenty of people started looking for them.

Anyway, I stumbled across this forum thread and made up my mind to share this discussion at SEJ by providing my own list of variables (the SEO perspective, please note that, like one of my best friends pointed out, this post is not intended as the list of search algorithm variables but rather as the list of SEO parameters) and asking you to contribute.

Parameters we are almost sure (with different level of confidence) to be included in the algorithm (for your convenience I linked some of them to our previous discussions on the topic):

I cant found download link
huh? this is not a software, he's just listing all possible factors/variables in the google PR algorithm, just copy and paste it to a word processor. This is a good post, reminds us of things that are really important and let's us see the big picture when optimizing our sites. We sometimes tend to focus on one factor only and scratch our heads when we do not rank well because of our tunnel vision:) Thanks marcostx9 :)

Now this is a great post!! What would be said if we were to truly find googles algorithm? now that would be MONEY!! However i suspect that will never happen and what are your opinions on the thought that to make it harder for us fellow BHW peeps is the possibility that they change the weight % of scored items so that there is no difinitive way to test for results..

I'm sure some google programmer whistle blower will release it someday. The thing is the algorithm has small changes. The 200 factors remain the same, but how much weight goes into those factors and how they relate change. It would be interesting if their was a search engine that had an open source algorithm and let everyone view it and use it, and modify it in their own way and upload their changes as alternate downloads.

I think it boils down to 5 main ideas. Content Quality, Usefulness of site, Trust, relevency and popularity.
Many of the 200 factors overlap these 5 main concepts. A site needs to be running with quality, reliable, relevent content. I think various filetypes within the site are good; tables, images, xls, pdfs, txts, wmv, mp3s, forms, and other files, but only if the server can handle the loads, and only if they're seen as useful (linked to).
Trust is a big issue, but if you get enough links in a "natural" way, you will be seen as more trusted, and if you have anchor text in links you will be seen as more relevnt.

I also think location of search, and searchers preferences are playing more into the results as well as google is trying to adapt the search results for the user.

Man that is a a lot of reading. Ugh and I'm my way to dreamland. I'm going to follow this as I believe it fills pieces of the puzzle we wonder about. The big G is like the deathstar but we don't want to kill it. We just don't want to be squashed like some sidewalk bug and get sandboxed.

Matt Cutts is full of shit, you should all know.

He just puts out what he does to discourage blackhat SEOers and keep Whitehats (mostly people on DP) under his thumb.

Any truth he leaks out is tightly controlled.

All you really need is to
A. Get indexed and
B. get high quality inbound links. QUALITY NOT QUANTITY!

A quality link is a link from a non-spammy source. Google ignores nofollow I hear, so it'd be best to consider social sites as well as related topic blogs and high ranking related pages linking back as quality.
