1. http://www.twittergrader.com is a quick way to see your Twitter stats, and how you compare with the rest of the tweets on the Internet.
2. http://www.Bit.ly is a good way to track who retweeted or forwarded and clicked on your links. But this only works if you use the Bit.ly url shortener when you send out Tweets. If you use Tweetdeck to send and read Tweets, then you can choose Bit.ly as your default URL shortener.
3. http://backtweets.com/ is great at showing you who’s been talking about you. Type in a link into backtweets, and it will show you the recent history of that link, even if it’s been turned into a tiny url, or if they’ve left your name off the Tweet.
4. http://www.Klout.com ranks who the biggest Twitter users with the most reach are (clout, in other words). It will rank where you stand as well, and graphs your Twitter name on a chart, much like a Myers-Briggs tests, rating you on where your site falls on the web based on all sorts of factors. A really cool aspect of the site is that it ranks people on individual topics as well, like who are the most respected Twitters on social media, etc. This would be a great way to figure out whom to follow in your industry.
