TL;DR: SEO ROI = (Revenue from SEO - Cost of SEO) / Cost of SEO × 100. But attribution tricky. Use: organic conversion value vs SEO spend. Also: brand value, market share, cost savings vs ads.
Direct ROI Formula
- Organic traffic × conversion rate × AOV = Organic revenue.
- Organic revenue / SEO cost = Revenue multiple.
- (Revenue - Cost) / Cost × 100 = ROI %.
Example:
- 10,000 organic visits × 2% conversion × 500 ₪ AOV = 100,000 ₪.
- SEO cost: 10,000 ₪.
- ROI: 900%.
Beyond Direct Revenue
- Brand searches (value hard to quantify).
- Customer acquisition cost (SEO vs ads).
- Market share (visibility).
- Long-term customer lifetime value.
