- Calculating SEO ROI
Marketing ROI is the ratio of revenue generated by marketing to the cost of marketing activities. Calculating it accurately requires: clear revenue attribution, complete cost accounting, and consistent measurement timeframes. Most businesses either cannot calculate their marketing ROI or calculate it incorrectly.
The Basic ROI Formula
ROI = (Revenue from marketing - Marketing costs) / Marketing costs × 100. A 200% ROI means you generated ₹3 in revenue for every ₹1 spent — or 3x return. Healthy digital marketing ROI targets: Google Ads 300–500% (3–5x ROAS), Email 4,000%+ (₹40+ per ₹1 spent), SEO 300–900% once organic traffic scales.
Fully-Loaded Cost Accounting
Marketing cost must include: ad spend, agency/consultant fees, tool subscriptions, content production costs, and staff time. Under-counting costs inflates ROI, leading to underinvestment in operational capacity and overconfidence in channel performance.
Calculating SEO ROI
SEO ROI is the hardest to calculate because results compound over time. Method: (Organic traffic × conversion rate × average order value) - SEO costs = SEO revenue contribution. Compare against what paid traffic would cost for the same volume at your average CPC to quantify the true value.
