SEO ROI compares value attributed or estimated from SEO with the cost of the SEO work. A useful estimate states what counts as extra, which costs are included, and the period being measured. Revenue, contribution, and profit mean different things.
For this calculator, estimated ROI is the amount left after delivery costs and SEO costs divided by total SEO cost, expressed as a percentage. It is available only when SEO cost is greater than zero. The result depends on the assumptions entered and is not proof of causal impact.
Yes. If the modeled revenue after delivery costs does not cover the SEO costs during the selected period, the amount left and ROI can be negative. A negative estimate is still useful for testing assumptions and timing.
No. Organic-search revenue is a revenue measure. This calculator also subtracts delivery costs and SEO costs to estimate what remains. It counts only the additional outcomes represented by the inputs, not all existing organic revenue.
Choose a period that matches the business question and the timing of your sales or customer revenue. SEO traffic may take time to grow, and conversions may happen later. The calculator lets you set a growth period and projection period; it does not determine the right period for every business.
No. You provide the extra organic visits or choose an assumed percentage increase based on current visits. The calculator models the effects of that assumption; it does not forecast rankings or traffic.
Include the SEO spending you want the estimate to represent, such as agency fees, staff time, content, tools, and setup work. Add each cost once. Enter delivery costs separately so the estimate can distinguish the cost of fulfilling a sale from the cost of SEO.
Yes. Select Recurring revenue for SaaS, memberships, subscriptions, or monthly service retainers. Enter monthly revenue and delivery cost per active customer, the customer-loss rate, and when revenue starts. The result is sensitive to those assumptions.
No. It estimates the economics of the SEO estimate you enter. Paid-click replacement value is not included. A channel comparison needs separate assumptions about paid spend, traffic, conversion quality, and attribution.
