Clarity and focus. The best landing pages communicate their value proposition within seconds, remove navigation distractions, and guide visitors through a logical sequence of benefits, proof, and calls-to-action. Every section earns its place by addressing a visitor objection or reinforcing the core message.
Length should match the complexity of what you are selling. A simple free tool might need only a hero section and a sign-up form, while a premium service benefits from detailed feature explanations, testimonials, and pricing. Test different lengths with real traffic rather than guessing.
