Hi Nicole!

If you're only looking for a tool for Twitter engagement, I would recommend HootSuite. It's the best Twitter engagement tool that I've used so far and very easy to use. You can track mentions, keyword searches pertaining to your brand, industry and your competition and respond directly within the tool.

If you want to go beyond Twitter and track what people are saying about your brand across all social media channels, SDL SM2 (was Alterian SM2) is a great tool, but I am biased because I work there. If you have any more questions I'd be happy to help you more.
