What are some business examples that were/are based primarily on a new metric or algorithm, like Pagerank and Google?

This sounds like a homework question, but I'll bite. App store rankings based on downloads or ratings? http://dd508hmafkqws.cloudfront.net/sites/default/files/B8z3CahCQAALsU8.jpg http://dd508hmafkqws.cloudfront.net/sites/default/files/B8z3... Yelp ratings? http://www.avclub.com/tvclub/every-person-here-thinks-about-them-226886 http://www.avclub.com/tvclub/every-person-here-thinks-about-... Basically anything with a rating or ranking system where individuals contribute to an aggregate score and the highest scores get more attention, and if you get more attention you get more revenue/exposure/even more attention.

  Not a homework question. I am developing a new metric for reproducibility in scholarly publishing and trying to understand previous examples of successful models.

    Oh, well, pagerank is based off ranking published papers anyway: https://en.wikipedia.org/wiki/Citation_analysis https://en.wikipedia.org/wiki/Citation_analysis

        There are two questions you should be asking yourself: 1. Will a person in your target market, when cherry-picking a couple examples they care about, say "Wow, these results are way better than what I would've found myself!"? 2. Are there enough people in your target market to justify the economics of your system? Answer #2 first, and then put all your effort into making #1 come true. Google worked because everybody searches the web, and Google was clearly better than rival search engines. Many metric-based businesses fail because not enough people care about the metrics to make enough money; the remainder fail because they're not a noticeable-enough improvement on the status quo.
