Pixel ranking refers to the number of pixels between the position of your website on the Search Engine Results Page (SERP) and the top of the page. The goal is to have the lowest possible pixel position i.e. the minimum distance between the top of the page and your website position as this ensures that you are closer to the top of the page, and therefore will have better visibility on the SERP.
The standard number of pixels that make up the fold on desktop is 800 pixels and on mobile, is 400 pixels as depicted in the images below. In this article, we will use a desktop device (800 pixel makeup of the fold) to explain Pixel Ranking.
