But for some reason there really seems to have been a perfect storm for Twitter, as already some people have come up with some really valuable metrics to measure how well you are performing on the site.
Clicks per 1000 followers – Say Ashton Kutcher, with his nearly two million followers happens to retweet your post, how many visitors does he send? And how many relative to his overall community? Once you know who is sending you the most traffic you know who is worthy of some good old-fashioned schmoozing.
Follower velocity – Twitterholic and plenty of other tools can help you track accounts popularity over time. Understanding when you get upswings in followers can help you replicate that success in the future.
CTR (clicks vs. followers) – a favourite of mine which I’ll be using to judge the success of our recent Twitter whitepaper. Add up the number of clicks from twitter and divide by the total follower count of everyone who retweeted your content. Seeing the click thru rate will help you understand what topics are popular with visitors, not just the people retweeting!
Retweet Depth – If you release a cd single you can be sure your mum will buy a dozen copies; the people closest to you are always most likely to pay attention to your content. Getting people who aren’t your contacts to retweet your content is much more valuable than six contacts doing the same. And if those people are five steps away from you, it’s even more powerful.
