A vast wasteland that hardly anyone visits unless you are on a mobile phone then it is just continuous scrolling. HAHA
A long time ago in a land far, far, away you wanted to get your website ranked in the first three pages of Google but then the wizards of the land became so good that you had to be on the first page of Google because everyone started finding what they needed on the first page only. Then the wizards got better yet and you have to rank ‘above the fold’ on the first page of Google.
Above the fold means seeing the SERPs (search engine results pages) without having to scroll.
