The ROAS formula
ROAS stands for return on ad spend. It measures how much revenue each dollar of advertising brings back: ROAS = revenue ÷ ad spend. A ROAS of 3 means $3 in revenue for every $1 spent.
Why break-even ROAS matters more than ROAS
Revenue is not profit. A ROAS of 2 is excellent for a product with an 80% margin and a loss for a product with a 40% margin. Your break-even ROAS is 1 ÷ gross margin. Use it as the line your campaigns have to clear, and judge every channel against it.
How to raise ROAS on cold traffic
Most brands try to fix ROAS in the ad account: new creatives, new audiences, lower bids. The bigger lever often sits after the click. When cold traffic lands on a page that explains the problem and the product before asking for the sale, conversion rate and order value go up together. That is what an advertorial does. One of our clients went from a 0.3 ROAS on product-page traffic to a stable 3.0+ this way.
