One of the questions businesses ask most often is: How should we measure Twitter? That’s an impossible question to answer universally, because what you measure—be it volume of retweets, uses of a hashtag, percentage of click-throughs, revenue from coupon code conversions, sentiment of users, or something else altogether—depends entirely on your goals. But a few services can get you started, and these are worth trying:

1. Crowdbooster (http://crowdbooster.com), which provides a suite of analytics, also finds links and content that might be a good fit for your audience, and it tells you the best times to tweet. The service has free and paid options.

2 and 3. RowFeeder (http://rowfeeder.com) and Sprout Social (http://sproutsocial.com) both have good reputations for providing some basic free reports and analytics (they both have paid options, too.).
