You've heard that prompt engineering is the key to getting good results from ChatGPT, Claude, and other AI tools. But most advice treats it like a mystical art form with complicated frameworks and memorized templates.
The truth is simpler. Five prompt formulas cover most of what a business owner needs to do with AI. Learn these five, and you will spend less time staring at an empty text box.
Formula 1: The Role + Task Formula
Best for: Content creation, analysis, strategy work
The structure: "You are a [role]. [Task description]. [Output format]."
This is the most versatile formula in the set. By giving the AI a specific role, you immediately narrow its frame of reference. A "marketing copywriter" writes differently from a "financial analyst," even when given the same task.
Example:
You are a senior copywriter specializing in email marketing for B2B software companies. Write a 5-email welcome sequence for a project management tool aimed at small teams. Each email should be 3-4 sentences. Use a conversational tone and focus on the pain point of scattered communication.
Without the role, ChatGPT defaults to generic instructional content. With the role, you get targeted, industry-specific copy that sounds like it was written by someone who understands your audience.
Variation: Add experience level to the role. "You are a senior accountant with 15 years of experience at a mid-size CPA firm" produces more practical, nuanced advice than "You are an accountant."
Formula 2: The Fill-in-the-Blanks Formula
Best for: Templates, emails, proposals, social media posts
The structure: "Help me write a [document type]. Here's the situation: [context]. Here are the blanks to fill: [variables]."
This formula treats the AI like a smart template engine. You provide the structure and the raw materials; the AI fills in the gaps with coherent prose.
Example:
Help me write a project proposal for a website redesign. Here's the situation: A local bakery wants to add e-commerce to their existing informational site. They need product pages, a shopping cart, and payment integration. Their budget is $5,000. Their timeline is 8 weeks. Here are the blanks to fill: project overview, scope of work, timeline, pricing breakdown, and next steps. Write it in a professional but warm tone.
This works because you maintain control over the key inputs (price, timeline, deliverables) while letting the AI handle the prose. It's ideal for any document where you have the facts but struggle with phrasing.
Formula 3: The Reverse Brainstorm Formula
Best for: Problem-solving, troubleshooting, risk analysis
The structure: "I want to [goal]. Here's what I'm considering: [approach]. Tell me everything that could go wrong, and what I should do instead."
Most people use AI to brainstorm "what should I do." This formula flips the script and asks for what not to do. It's surprisingly effective because AI models have been trained on countless case studies, failure postmortems, and cautionary tales.
Example:
I want to improve our company's social media presence. Here's what I'm considering: posting daily on all major platforms and using trending hashtags. Tell me everything that could go wrong with this approach, and what I should do instead for a small business with limited time.
The AI will likely point out that daily posting on all platforms is unsustainable, that chasing trends dilutes brand identity, and that a focused strategy on one or two platforms with quality content would be more effective. You get the benefit of experience without making the mistakes yourself.
Pro tip: Follow up with "Now, tell me the top three strategies that actually work for small businesses like mine." This gives you both the warnings and the solutions in one conversation.
Formula 4: The Before-After-Bridge Formula
Best for: Sales copy, marketing, landing pages, value propositions
The structure: "Write [document] for someone who [before state] and wants [after state]. The bridge is [your product/service]."
This formula is borrowed from direct-response copywriting. It works because it forces the AI to address the emotional transformation your customer experiences, not just the features of your product.
Example:
Write a landing page headline and subheadline for a time-tracking app. Write it for someone who is losing 10 hours per week to manual timesheets and wants to reclaim that time for billable work. The bridge is our app that automates time tracking with one click.
The AI will lean into the pain (lost hours, frustration) and the gain (reclaimed time, more revenue) rather than listing features like "automatic tracking" or "integrations." This is the difference between copy that converts and copy that sounds like a spec sheet.
Variation: Use it for internal communication too. "Write a memo to the team about adopting a new CRM. They are frustrated with the current system (before) and want a single source of truth (after). The bridge is Salesforce."
Formula 5: The Constraints-First Formula
Best for: Strategic decisions, prioritization, trade-off analysis
The structure: "I need to [decision]. Here are my constraints: [list]. Given these constraints, what's the best option and why?"
AI models tend to give you the "ideal world" answer unless you explicitly constrain them. This formula forces the AI to work within your real-world limits: budget, time, team size, technical skill, or whatever else applies.
Example:
I need to choose a CRM for my 8-person real estate team. Here are my constraints: (1) Budget is $100 per month total. (2) The team is not technical and needs minimal setup. (3) We need email integration and pipeline management. (4) Must work on mobile. Given these constraints, what's the best option and why?
Without the constraints, the AI might suggest Salesforce or HubSpot Enterprise — powerful but expensive and complex. With the constraints, you get practical recommendations like Pipedrive or Zoho that fit your actual situation.
Pro tip: Add a negative constraint: "Exclude options that require long-term contracts." This filters out subscription traps.
Putting the Formulas Together
These five formulas aren't mutually exclusive. You can combine them for even better results:
Role + Constraints + Before-After-Bridge:
You are a SaaS copywriter. Write pricing page copy for a project management tool. Our customers are overwhelmed by complex tools (before) and want simplicity that actually ships projects (after). The bridge is our "less is more" design philosophy. Constraint: No jargon. Write at an 8th-grade reading level. Highlight the 14-day free trial.
That prompt has role, transformation, and constraints baked in. The result will be dramatically better than "write pricing page copy for a project management tool."
Your Prompt Workflow
Here's how to turn these formulas into a repeatable process:
- Identify your goal. What specific output do you need? (Email, strategy proposal, landing page, analysis)
- Pick the formula. Match your goal to the formula above.
- Write the prompt. Use the formula structure with your specific details.
- Review and refine. Read the output. Does it match what you wanted? Add or remove constraints.
- Save winning prompts. When you get a great result, save it as a template. Next time, just swap out the details.
Common Prompting Mistakes
Even with these formulas, a few mistakes can sabotage your results:
- Being vague. "Write something about our product" produces generic fluff. Concrete details produce concrete results.
- Asking multiple questions at once. One prompt, one task. If you need several things, break them into separate prompts.
- Not specifying length. "In 3-4 sentences" is clearer than "make it brief." "500 words" is clearer than "write a detailed post."
- Accepting the first result. The first output is rarely the best. Iterate. The conversation is part of the prompting process.
Summary
You don't need to memorize dozens of prompt engineering frameworks. These five formulas — Role + Task, Fill-in-the-Blanks, Reverse Brainstorm, Before-After-Bridge, and Constraints-First — will handle the vast majority of what a business owner needs to do with AI.
Pick one, use it today, and notice the difference in quality. Once it feels natural, add another. Within a week, these structures will become second nature, and you'll wonder how you ever typed "write an email" into that text box alone.
