A concise headline naming the problem solved, a supporting subheading with specifics, a prominent call to action (typically "Start free trial" or "Book a demo"), and an adjacent product screenshot or short animation form the most effective hero pattern. Keeping the hero focused avoids decision paralysis.
Extremely important. Prospective buyers want to see the interface they will be using before committing. Polished, annotated screenshots placed in context -- such as within a browser or device frame -- feel more credible than abstract illustrations that avoid showing the actual product.
