A hero section is a 5-second contract.
Headline answers 'what do I get'. Subhead answers 'why now'. One CTA — never two. One trust signal above the fold. Numbers beat adjectives.
Found this rule by auditing 50+ funded SaaS landings. The median sits between 50-70 on mobile Lighthouse — and the hero is where the bleeding starts.
