Conversion rate is the percentage of visitors who take a desired action — signing up, subscribing, purchasing, or any goal you define. It measures how effectively your product turns interest into action. For vibe coders, conversion rate tells you whether your landing page, onboarding, and pricing are working.
Conversion rate is the number that tells you if your product's messaging, design, and value proposition are resonating with users.

AI can help generate landing page variants, but conversion optimization requires watching real user behavior. Set up analytics (like Plausible) early and let data guide your decisions.
