What it means
ROAS is revenue attributed to ads divided by ad spend. A ROAS of 4 means four pounds of revenue for every pound spent.
Why it matters for your business
Revenue is not profit, so ROAS should be judged against your margins. For service businesses, tracking enquiries through to won jobs in a CRM is what makes ROAS meaningful.
