Return on Ad Spend (ROAS) is a metric measuring the revenue generated for every dollar spent on paid advertising, calculated by dividing total revenue from ads by the total amount spent on those ads.
While ROAS is primarily a paid media metric, it’s a useful comparative benchmark for evaluating SEO’s relative efficiency, since organic search typically has no direct per-click cost, meaning organic “ROAS” is effectively unlimited once initial investment costs are recovered.
Businesses running both SEO and paid advertising often use ROAS alongside organic ROI to make informed decisions about how to allocate marketing budget across channels over time.
We help businesses understand this comparative context as part of our SEO Audits & Reporting service.
