The IM experts tend to say the most important metric to watch out for is conversions (CPA).
I have two questions for ya:
1) When you tried various paid marketing strategies (offline & online), which type of marketing tends to cost you low CPA compared to others?
2) DMA (direct marketing association) found Email Marketing as lowest CPA and Internet Display as highest CPA (see the image below). Do you agree with DMA's chart?
