For the most part, I understand StumbleUpon.com, and certainly since receiving great reviews and excellent ratings, I very much appreciate Stumble Upon.
After limited research, I have not been able to find significant information regarding the specifics of the system and algorithm used by Stumble Upon to garner a sites’ star rating, which star you are rated at and why, and at what level your site/page is served to participating Stumblers as they Stumble. I am sure that the number of Stumbled page views, subsequent ratings, whether thumbs up or down, play a majority role, but at what level?
More specifically, I have the following questions:
1) How are sites/pages given a star rating? What is that rating based upon? How can a rating be affected positively or negatively?
2) Is there a more refined directory of pages that have been stumbled? For instance, Atilus.com has many Stumbled pages with varying ratings, so where is a list of those pages so that I can actively monitor success?
I would love to understand this excellent service more. Can anyone offer me insight on this topic? Please provide me and my readers with as much information as possible, and I will personally respond to all those that post.
