The view website visitors see when they land on your website, without scrolling.

On most websites, the above the fold view includes the top navigation bar, and the hero image section.

These are the prime pieces of web real estate that all web visitors will be able to see -- without scrolling.

Back in the "olden days," before rapid adoption of mobile devices, placing key information above the fold was a crucial web practice. With so many users now surfing the web on mobile, scrolling is a necessary user behavior.

But, you still can't count on your visitors to scroll below the fold. And, even if they do, you never know how far down the page they'll get.

That's why it's still considered a best practice to feature your most important information above the fold -- because you can't be certain your visitors will scroll, below the fold, to take in more of your website.
