Every time I shared a landing page for feedback, I got the same useless responses:
- "Your headline could be clearer"
- "Add more social proof"
- "The CTA isn't strong enough"
Great. But which headline? What kind of social proof? How do I fix the CTA?
Vague feedback doesn't convert visitors into customers. Specific feedback does.
PageRoast — an AI tool that scores your landing page across 6 conversion dimensions and gives you the exact fix for each one.
You paste your URL and page copy, and you get back:
- An overall conversion score (0–100)
- A breakdown across 6 dimensions: Clarity, ICP Fit, Pain/Outcome Framing, CTA Strength, Social Proof, Objection Handling
- The specific problem on your page for each dimension (quoting your actual copy)
- A concrete rewrite or fix for each issue
- Your single biggest conversion killer
The Stack:
- Frontend: Vanilla HTML/CSS/JS (keeping it simple)
- AI: Claude API (claude-haiku for speed)
- Backend: Netlify Functions (serverless, zero config)
- Email capture: Airtable via a Netlify Function
- Hosting: Netlify
The whole thing took a weekend to build and costs less than $0.01 per analysis to run.
The Interesting Part — The Prompt
The hardest part wasn't the code, it was the prompt. Generic AI feedback is just as useless as human feedback. The key was building a structured rubric that forces the model to:
- Quote the actual copy when identifying a problem
- Give a concrete rewrite, not just "improve this"
- Return consistent JSON so the UI can display it cleanly

Would love feedback from this community — especially on the prompt or the tech stack. What would you have done differently?
