Most ROI models for professional services assume a single transaction. A law firm wins a case. An accountant files a return. The engagement ends. Therapy doesn't work that way.
When a patient enters your caseload, they typically attend weekly or biweekly sessions across months — sometimes years. That recurring structure changes the economics of every marketing channel you evaluate, including SEO.
Consider a simplified example using round numbers you can replace with your own:
- Session rate: $150 (self-pay) or your average insurance reimbursement
- Average session frequency: biweekly (26 sessions per year)
- Average retention: 12 months (conservative for many presenting concerns)
At those figures, one new retained patient represents roughly $3,900 in annual revenue. A patient who stays 18 months represents closer to $5,850. These are illustrative figures — your numbers depend on your rate, payer mix, and presenting population.
The implication is significant: if your SEO investment is $1,500 per month, you need fewer than one new long-term patient per month to cover the cost. Everything beyond that is margin. This is why therapists who run the full LTV calculation often reach a different conclusion about SEO than practitioners who only look at cost-per-click comparisons or upfront fees.
