Most business websites are brochures. People read, nod and leave, and you never learn who was interested.
A business tool does something for the visitor: a score, a quote, a recommendation. It's useful, so they finish it.
They get their answer. You get their name, WhatsApp number and need, while you sleep.

AI builds what you describe, so the skill is describing it well. John's RAO method gives every prompt three parts: a Role, an Action and the Operational context.
RoleYou are a product designer building a lead tool for a CA firm in Chennai.
ActionBuild a 6-question GST readiness check that scores the visitor out of 100.
Operational contextVisitors are small business owners on their phones. Plain English. Ask for name and WhatsApp number before the full result.
You don't need to be technical. You need to know your customers. That's the part AI can't do for you.
