What metrics are calculated in the Tracker?
The Tracker calculates the same metrics available in the standard TweetReach reports – reach, exposure, number and type of tweets, Twitter users, etc… These data are broken down over time so you can view trends and variations. In addition, the Tracker provides information about each tweet in the report, including how many times it was retweeted and how many impressions that tweet generated. You can see the most retweeted tweets, and the tweets that generated the highest exposure. In addition, the Tracker includes detailed contributor metrics like Klout score, number of followers and more. There are detailed reports for hashtags and URLs, including bit.ly clicks.
