How to read it

CPM is the price per 1,000 subscribers: price ÷ subscribers × 1,000. Not everyone opens, so effective CPM divides the price by estimated opens instead, which is closer to what you pay to actually be seen. Clicks, conversions and ROI follow from the rates you enter, so they're only as good as those rates. Ask the publisher for open and click rates from recent issues before you book.
