Free SEO ROI Calculator

Subtract your SEO cost from the revenue organic search produced, then divide by the cost and multiply by 100. Three thousand spent returning nine thousand is a 200% return. The difficulty is never the formula, it is attributing revenue honestly.

Six to twelve months is realistic for a competitive term, and four to twelve weeks for genuine long-tail. Anything promising page one in thirty days is either targeting terms nobody searches or is about to do something you will regret.

Use the organic channel report in your analytics with a conversion goal attached, and compare against a pre-SEO baseline. Remember branded search would largely convert anyway, so segment it out if you want a defensible number.

Yes. Writer fees, editor time, design, developer hours for technical fixes and any tool subscriptions all belong in the investment figure. Counting only the agency retainer produces a return figure that will not survive scrutiny.

Because the cost is largely front-loaded and the asset persists. A page that took a thousand to produce may earn for years without further spend, so the same investment keeps appearing in the numerator while the denominator stays fixed.

Paid buys traffic immediately and stops the moment you stop paying. SEO costs more up front and compounds afterwards. Mature organic programmes routinely beat paid on return, which is precisely why they take so long to reach that point.

Model it with a conservative assumed conversion rate, typically 1 to 2% for ecommerce and 2 to 5% for lead generation, then treat the output as a range rather than a forecast. It is still useful for deciding whether the channel is worth entering.

Ideally yes, using a data-driven or position-based attribution model. Last-click attribution systematically undervalues SEO, because organic search often introduces the visitor who later returns through a branded search or a direct visit to buy.

That you are spending more than the channel returns right now. Early on that is expected and not alarming. It becomes a problem if it persists past twelve months with no upward trend in rankings, impressions or traffic.

No, and treating it as one is a common trap. Traffic to pages with no commercial intent can rise substantially while revenue does not move at all. Always tie the calculation to conversions and revenue rather than sessions.
