What’s a good CPM rate?
A “good” CPM rate is entirely dependednt on the ROI of what you’ve spent. For example, in general retail you may want a CPM below or around $1.39. But if you aren’t meeting your marketing objectives, it may not really matter. If you market is CEOs of Fortune 100 companies, you may be willing to pay 10X as much because your ROI would still be positive.
