WhyNotConverting
A free landing page audit tool that scores your site 0–100 for conversion readiness, identifies friction points ranked by impact, and gives you specific fixes, all in around 30 seconds and with no signup required.
The problem
Most founders know their landing page isn't converting well but can't afford a CRO consultant, don't have time to read a 40-page audit, and don't trust generic checklists. They want a specific answer, fast.
What I built
WhyNotConverting takes a URL, fetches the page, and runs it through a structured LLM analysis that evaluates headline clarity, value proposition strength, trust signals, CTA placement, mobile UX, and a dozen other conversion factors.
The output is a numeric score (0–100) plus a prioritised list of friction points, each one with a specific fix rather than a vague observation. No account, no email, results in under a minute.
Technical highlights
The audit runs entirely server-side: the URL is fetched, HTML is cleaned and passed to the LLM with a structured prompt, and the response is streamed back to the user so they see results appearing in real time rather than waiting for a full response.
The scoring rubric is baked into the system prompt as a weighted evaluation framework, so the LLM produces consistent, comparable scores rather than free-form prose.
