Largest Contentful Paint (LCP)
Measures loading performance by timing when the main content element (image or text block) becomes visible to users.
Largest Contentful Paint (LCP) estimates perceived load speed by measuring when the largest content element in the viewport—often a hero image or headline—renders. Good LCP correlates with lower bounce and higher engagement. It matters because users quickly abandon slow pages, and LCP contributes to page experience signals. LCP influences image strategy (compression, dimensions, priority hints), server performance, and critical CSS delivery. Addressing heavy hero assets and render‑blocking resources typically yields the largest gains.
- Optimize hero images and fonts
- Inline critical CSS and defer non‑critical JS
- Context
A blog template loads a 1.5MB hero image.
- Action
The team serves next‑gen formats, sets width/height, and preloads the hero.
- Result
LCP drops to 2.2s; time on page and scroll depth increase across articles.
