What it is
MER, the marketing efficiency ratio, divides all of your store's revenue by all of your marketing spend. It does not try to decide which ad caused which sale. It asks a simpler question: for every dollar spent on marketing, how many dollars of revenue came in?

The formula
MER = Total net sales ÷ total marketing spendHow to read it
Watch the trend rather than a single week. If spend goes up and MER holds, the extra budget is working. If MER falls as spend rises, you are buying sales at a worse rate. Because it counts every order once, MER is harder to inflate than platform ROAS.
