Great spot sam. You know the market is maturing when their are tools that allow ranking. Interesting to see news.yc at 92 and ycombinator 82 and joelonsoftware 98.
I'd be extremely interested to see their algorithm.
I wonder how related it is to the SEO type page optimization calculators - it seems not much. My "seo optimized" sites have a lower ranking (30-60) than my highly trafficked site (80).
According to the page: The algorithm uses a proprietary blend of over a dozen different variables, including search engine data, website structure, approximate traffic, site performance, and others.
Glad some of you are finding the Website Grader tool somewhat useful. It started out as a simple experimental project (basically I wanted something to meet my own needs).
Since then, it's taken on a bit of a life of its own.
The algorithm is basically trying to to simulate the same kinds of things I look for when trying to assess a site (a combination of traffic, SEO, site structure, popularity and other things). I'm making another big update to the underlying software within the next week or so.
If you have ideas for improvement, please leave a comment (either here or preferably on the websitegrader.com site itself).
