You built a landing page in an afternoon. You tweeted it. Traffic came. Nobody signed up. It's not the traffic — it's the page. Here's what's almost certainly wrong.
1. The hero doesn't say what the product does
AI-generated heroes love abstractions. "Transform your workflow." "Unlock your potential." "AI-powered productivity for the modern team." A visitor should know, in under 2 seconds, what your product literally does. Rewrite the hero as: [Product] lets [audience] do [specific thing] without [specific pain].
2. The CTA is "Learn more"
"Learn more" is what you say when you have nothing to offer. Replace it with the actual action: "Roast my landing page," "Generate my first invoice," "Book a 15-minute call." Verbs that describe the outcome, not the process.
3. There's no proof
Vibe-coded pages are almost always launched without a single testimonial, logo, screenshot of real output, or usage number. Add one piece of proof above the fold. A quoted DM, a Loom of the tool in use, a count of users, anything. First-time visitors need a reason to believe you.
4. The page is still on default typography and default colors
The Inter + indigo-500 + white background combo is the visual equivalent of a template watermark. If your page could belong to any of ten thousand other AI-built apps, it will be treated like one. Pick one accent color that isn't blue or purple. Pick one display font that isn't Inter or Poppins. That's 80% of visual differentiation done.
The 5-minute fix
Paste your URL into WeVibe.fail. You'll get a per-metric breakdown — copy, CTA, credibility, design, security — plus a roast. Fix the two lowest metrics. Ship again. That's the whole playbook.
