The block visitors see first, before any scrolling. It typically pairs a small badge, a large headline, a supporting subhead, one or two CTA buttons, and a product visual — screenshot, illustration, or animation.
Write the headline so a visitor understands what the product is for within five seconds. The subhead adds one more line — who it's for, or what makes it different. The primary CTA gets the accent color and visual weight; a secondary CTA ("Watch demo") stays outlined or ghost so it doesn't compete.
Vague headlines ("Build a better future") convert worse than specific ones. Button copy that states the outcome ("Try it free") beats generic verbs ("Get started"). And an overly busy visual can undercut the headline's readability instead of supporting it.
When to use
The opening block of virtually every marketing or landing page. If a page serves multiple products or audiences, vary the headline per page to match the traffic source.
