SEO ROI

SEO ROI (Return On Investment) measures the profitability of investments in organic search. Its calculation compares revenues generated by organic traffic (sales, leads, subscriptions) to costs incurred (tools, content creation, link building, consulting). The basic formula is: ROI = (Organic Revenue - SEO Cost) / SEO Cost x 100. The calculation is complex because SEO results are cumulative and unfold over time. Unlike SEA where each click is measurable, SEO is a long-term investment whose profitability increases over time because acquired organic traffic persists without additional cost.
