SEO as a Strategic Capital Asset
Search engine optimization (SEO) is positioned not just as a marketing activity in the modern digital ecosystem, but as a strategic capital asset that gains value over time on business balance sheets and provides cumulative returns. While traditional digital advertising models stop traffic flow the moment spending stops; SEO functions as a growth engine that offers sustainable returns with minimum ongoing investment when structured correctly.
Basic SEO ROI Formula
SEO ROI = ((Revenue from SEO − Total SEO Cost) / Total SEO Cost) × 100
For example, if you invest 10,000 TL in a six-month period and generate 50,000 TL in revenue, your ROI is 400%. That is, every 1 TL investment brought you 4 TL net profit.
Comparative Financial Metrics: ROI and ROAS
