We run an SEO agency for mid-market B2B SaaS companies, but our marketing messaging currently sounds like every other agency. I want to build a high-converting result-based guarantee framework based on 80/20 principles. Please generate a complete breakdown that defines our ideal buyer persona and time-bound goals, translates our core service deliverables into actual business results with evidence, crafts a conditional guarantee statement including a meaningful seller penalty, and details the necessary risk controls like buyer commitments and operational guardrails.

Use this skill to turn vague positioning into a specific promise for a specific buyer under specific conditions. It is based on 80/20 Sales and Marketing by Perry Marshall.
Primary source: 80/20 Sales and Marketing, chapters 8 and 13.
Capture:
The USP should not try to persuade everyone. It should make the right buyer feel seen and the wrong buyer opt out.
List what the seller does, then translate it into what the buyer gets.
