I always get asked about what you are supposed to measure on Twitter, aside form the obvious things like Follower numbers, number of Twitter Lists you are on etc. For example why does Twitter reach, relevance and frequency really mean?
I came across a good post by FreshNetworks, who looked at this exact issue in their post. They produced an easy to follow presentation explaining the four areas you should be looking at. I have put these four areas together in one image, so you can easily see the different measurements you can extract via Twitter and what they really mean, below.

Any clearer now?
There are many tools that you can use to measure the areas mentioned above, some of which are in the Slideshare presentation (link above).
