SEO ROI compares the revenue or profit generated by organic and AI search visibility with what you spend on it. The hard part is attribution: tracking calls, forms and bookings back to search, and accepting that some AI-driven visits arrive without a click.

A simple ROI frame
| Input | How to measure |
|---|---|
| Cost | Fees, content, tools, internal time |
| Leads | Calls, forms, bookings from organic search |
| Value per lead | Close rate times average customer value |
| Return | Leads times value per lead, minus cost |
The AI search complication
Some customers see your name in an AI answer and then call directly or search your brand. Tracking branded searches and asking "how did you hear about us?" captures part of that.
Our expert view
We agree an ROI method with clients at the start. Changing the method later makes results impossible to judge.
