Visitors form judgments about your landing page within 50 milliseconds (Nielsen Norman Group). They decide whether to stay or leave within 5 seconds (Lindgaard et al., 2006). Above-the-fold conversion accounts for an estimated 70% of the final conversion outcome — the rest of the page is mostly downstream of decisions already made. Your hero section is the highest-leverage real estate on your entire site.
The data below covers headline patterns, CTA placement, visual hierarchy, the 5-second test, and what separates top-quartile heroes from the median across our 1,000-page analysis. Sources: NN/g, CXL, Baymard Institute, Wistia, Microsoft Research, and roast.page's own structural data.
