I learned about a new link count aggregator yesterday called Socialmeter, pointed out by Valdis Krebs on his blog Networking Weaving. It's petty straight forward, scanning a number of search engine and social bookmarking sites, in order to aggregate the count of inbound links for a given site. We can think of these links as "votes" in terms of popularity. I've thought the following metrics to be helpful for evaluating website value: - # unique visitors per day/week/month - # return visitors per day/week/month - time spent on website (or webpage) - # feed subscribers It seems like link counts is another useful metric to evaluate a website's value. Technorati has done this for some time now, but for blogs, and my understanding is that the given blog would have to be registered on Technorati. Socialmeter appears to be much more sweeping across the web universe. Here is the URL if you are interested to check it out: http://www.socialmeter.com/index.html
