Above-the-Fold vs Below-the-Fold Content Prioritization
The practice of deciding which page elements appear before scrolling versus after, based on user attention and conversion impact.
Content prioritization refers to the strategic decision of what information, imagery, or calls-to-action a user sees immediately upon landing on a page, versus what is pushed further down and requires scrolling. Because attention and drop-off are highest in the first few seconds of a page visit, teams often treat the initial viewport as premium real estate reserved for the message or action most likely to drive conversion.
This matters in CRO because not every visitor scrolls, and those who do scroll fast and skim. If a critical trust signal, price, or value proposition is buried below a long block of decorative content, a meaningful share of visitors never see it. At the same time, cramming too much into the initial view can overwhelm users or crowd out the primary call-to-action, so prioritization is a genuine trade-off exercise, not simply 'put everything at the top.'
A typical example: an e-commerce product page might test moving the shipping-and-returns reassurance line from the bottom of the description into the initial viewport, on the theory that shipping cost anxiety is a top reason for early abandonment. Teams often use scroll-depth and heatmap data to decide what genuinely needs to move up versus what can safely live further down the page.
The practice is closely related to information hierarchy in content strategy, but in a CRO context it's usually validated with A/B tests rather than opinion, since intuitions about what 'should' be prominent are frequently wrong.
