You want a guest to immediately think “I’m in the right place! Let me check out more!” The three questions your Homepage should answer: What do you do? Who do you serve? What makes you different from everyone else? Most people will skim over your Homepage before they pause to read any words.That’s why you should include images, a logo, and design elements that communicate who you are, who you serve, and what makes makes you different in a single glance.
The simple answer is: as long as it needs to be! There’s no "one size fits all" answer for page length. Some people see good results with simple full-screen slideshows. Others perform best with a long, scrolling, “one-page” feel that puts their most important information up front. Experimentation is your best tool for discovering exactly what your target market wants to see – and how much of it.
Start with a large, beautiful image (or several in a slideshow) and a to-the-point headline about your business. This lets people know they’re in the right place and entices them to see more. Other options to include are: images that link to deeper pages within your site, FX banners to add interest and break up the page, collages, sign-up forms, and text blocks that add vital searchable text.
