Metric

Marketing Efficiency Ratio (MER)

MER shows how much money you get back for every dollar you spend on ads and marketing. It's like checking if your ads are a good deal.

Formula MER = Total Revenue / Total Ad Spend

Why it matters

A high MER means your ads bring in lots of money compared to what they cost. This lets you spend more on good ads or keep extra money as profit, helping your online store grow and make more cash.
