What is SEO ROI?
A business case metric for content, technical SEO, and link programs. Attribution quality drives how trustworthy the number is.
- Use the same period for revenue and cost
- Cost includes labor, tools, freelancers, and content production
- Lag matters — SEO returns often trail spend
The Formula
Worked Example
Common Use Cases
- Budget reviews: justify SEO spend
- Agency reporting: period ROI snapshots
- Channel compare: SEO vs paid (carefully)
Pro Tips
- Prefer profit over revenue when COGS is high
- Document attribution model
- Show trailing windows (90/180 days)
Limitations: SEO ROI results are educational SEO planning aids—not guarantees of rankings or traffic. Search algorithms and attribution models vary.
