On a monthly basis, we provide total view counts and estimated calls counts for each of your Pro listings. Typically, estimated call counts are used to measure results.
We can report on how many calls your listing generated, but only you can decide the value of a call. Advertising has to make you more money then you are spending. Assessing the return on investment (ROI) of a Pro listing is a matter of multiplying the number of calls by the average per call value you assign. If that amount is greater than $330/year, then you win!
