Criteria for ranking a site.

[Greg-J]

I'm interested in knowing what criteria you believe makes a site more important to search engines. Specifically Google.

PR is an obvious measure of course, but what about indexed pages, or back-links? What other information that you can physically measure would you use to rank a site worth?

Thank you for that.

I'm more interested in what factors we can use from the search engines to rank a sites worth, or rather importance. I'm writing an algorithm similar to what dnscoop.com or the DP coop would use.

Site age, is it listed in DMOZ, number of edu and gov backlinks, compete ranking, number of outbound links, number of cached pages, strength of subpages..when comparing two sites this can get interesting. Site A has 8,000 indexed pages but none above PR 1, Site B has 3,000 indexed pages and 7 are PR 4. How will you quantify what is more important? That's where the creativity of the said algo comes in.

^agree with benahue i would also add how well are all of a sites indexed pages "themed" for a given search phrase and the allianchor of all incoming links

The dp coop uses age of site, dmoz listing, indexed pages, and traffic.

Greg - personally - you should have a plugin where it lets people enter the revenue per month in - so have the same thing as DNSCOOP does then allow a person to type in their revenue. Then the total value changes after that.
