If a display ad appears “above the fold,” this means that it:
- can be viewed in the upper portion of the page without scrolling
- will appear at the top of each page of the website
- will appear anywhere on the front page of the website
- takes up more than 20% of the webpage
If an ad is immediately visible after page load then it is considered above the fold. If you have to scroll down to see the ad then it is below the fold.
