ROAS (Return on Ad Spend) is the total revenue attributed to the ads divided by the amount spent on those ads. For example, if you spend $1,000 and generate $5,000 in attributed sales, your ROAS is 5x.
Important: ROAS is based only on revenue that can be attributed to the ads. Since pixel attribution is incomplete, actual revenue and true ROAS are often higher than what the platform reports.
