Vad är Above the Fold?
Snabbdefinition
Above the fold syftar på det innehåll som är synligt på en webbsida utan att scrolla ned, som anses vara den mest värdefulla zonen i en webbsidas layout.
The term 'above the fold' originates from newspapers, where the most important headlines were placed above the physical fold of the paper. In web design, it refers to the content visible in the browser viewport before the user scrolls. This area varies based on the user's device, screen size, and browser configuration.
Above-the-fold content is critical for two reasons: first impressions and performance. Users form an opinion about your website within 50 milliseconds, based entirely on what they see above the fold. This content must communicate your value proposition, establish credibility, and encourage scrolling or action.
From a performance perspective, optimizing above-the-fold content is key to good Core Web Vitals scores. Largest Contentful Paint (LCP) typically measures an above-the-fold element — a hero image, headline, or feature graphic. Inlining critical CSS ensures above-the-fold content renders immediately, while below-the-fold content can be lazily loaded.
Modern responsive design means 'above the fold' looks different on every device. A desktop hero section might be a tall banner with text overlay, while the mobile version shows a condensed version with a smaller image. Designing and optimizing for multiple viewport sizes is essential.
Varför det spelar roll
Above-the-fold content determines whether users stay or leave. Studies show that users spend 80% of their viewing time above the fold. If your value proposition, navigation, and primary CTA aren't visible without scrolling, many visitors won't scroll to find them.
For SEO, Google's LCP metric specifically measures above-the-fold content rendering speed. Slow-loading hero images or complex above-the-fold layouts directly hurt search rankings.
Verkliga exempel
A SaaS homepage moved their primary CTA from below the fold to above it and saw click-through rates increase by 40%
A landing page optimized their above-the-fold hero image (from 3MB JPEG to 150KB WebP) and improved LCP from 4.5 seconds to 1.2 seconds
A B2B company's above-the-fold content had a corporate stock photo and vague tagline — replacing it with a clear value proposition and product screenshot increased demo requests by 25%
An e-commerce site ensured product images appeared above the fold on mobile by reducing their header height, decreasing the bounce rate on product pages by 12%

LCP (Largest Contentful Paint)
LCP mäter den tid det tar för det största synliga innehållselementet på en sida, som en hero-bild eller rubrik, att renderas fullständigt.
Core Web Vitals
Core Web Vitals är tre specifika mätvärden från Google som mäter verkliga användarupplevelser på webbplatser: laddningsprestanda (LCP), interaktivitet (INP) och visuell stabilitet (CLS).
Page Speed
Sidhastighet är ett mått på hur snabbt en webbsida laddar och blir interaktiv, vilket direkt påverkar användarupplevelsen och sökmotorrankningar.
Lazy Loading
Lazy loading är en teknik som skjuter upp laddningen av icke-kritiska resurser, som bilder under fold, tills de faktiskt behövs.
