Quick Case Example
A small SEO agency won a local e-commerce client. They quoted a $3,500 monthly retainer with a 6-month minimum, plus a 10% bonus on revenue increases over baseline. After three months, organic revenue rose 28 percent. The client extended the contract and agreed to increase the retainer by 20 percent. The combination of a reasonable retainer and a measurable bonus sealed the long-term relationship.
Common Objections and How to Answer Them
- "That sounds expensive." Explain outcomes and show the cost per lead compared to paid channels.
- "We can do this cheaper in-house." Ask about capacity, time to ramp, and opportunity cost.
