Calculator
See exactly how much revenue your SEO efforts generate — and whether the investment is worth it.
What Is SEO ROI and How Is It Calculated?
SEO ROI measures the return you get from your search engine optimization investment. It answers the fundamental question: is the money you spend on SEO generating more revenue than it costs?
The formula is straightforward: take the revenue generated from organic search, subtract your SEO costs, divide by those costs, and multiply by 100. A positive ROI means SEO is profitable. A negative ROI means you need to adjust your strategy.
Unlike paid advertising where ROI is immediate and linear, SEO ROI compounds over time. Content you create today continues generating traffic and revenue for months or years, making the long-term ROI of SEO significantly higher than most other channels.
