Methodology
We convert traffic to customers, apply value and margin, then model ramp-up and confidence to estimate ROI.
- Benefits are gross profit: revenue × gross margin.
- Ramp-up reflects how quickly SEO gains reach full impact.
- Confidence/realization keeps estimates conservative.
- NPV discounts future cash flows at your chosen rate.
Common pitfalls
- Assuming all organic traffic converts at the same rate.
- Ignoring sales cycle delay and lead quality variance.
- Overstating value by mixing ACV and LTV without clarity.
- Double-counting assisted conversions across channels.
