Content Delivery Network—a distributed network of servers that delivers web content from locations geographically closest to each visitor. CDNs dramatically reduce latency and load times for global audiences while providing redundancy if one server fails. Framer hosts all sites on a global CDN automatically, ensuring fast performance worldwide without additional configuration.

The process of reducing image file sizes while maintaining acceptable visual quality for faster page loads. Optimized images can be 10x smaller than originals without noticeable quality loss, dramatically improving performance. Framer automatically optimizes uploaded images, converting to efficient formats like WebP where supported.

A technique that defers loading of off-screen content until users scroll near it, improving initial page load time. Lazy loading is especially valuable for image-heavy pages and infinite scroll implementations. Framer implements lazy loading automatically for images fold">below the fold.

A measure of how quickly page content loads and becomes interactive, influenced by file sizes, server response, and code efficiency. Google uses page speed as a ranking factor, making optimization both a UX and SEO concern. Framer's infrastructure and automatic optimizations help achieve fast page speeds.

Generating HTML on the server before sending to browsers, improving initial load performance and SEO. SSR provides complete content to search engines and faster first paint for users. Framer uses server-side rendering for optimal performance and SEO.

Temporary storage that keeps copies of files locally to speed up repeat visits, reducing the need to download the same resources again. Effective caching dramatically improves page-load">page load times for returning visitors. Framer's CDN handles caching automatically, serving assets from edge servers closest to each visitor.

The maximum rate of data transfer across a network connection, measured in bits per second. Higher bandwidth allows faster loading of large assets like images and videos, directly impacting user experience. Optimize bandwidth usage by compressing images, lazy loading off-screen content, and leveraging Framer's automatic performance optimizations.

The process of storing frequently accessed data in temporary storage for faster retrieval on subsequent requests. Browser caching stores assets locally while server caching reduces database queries and processing time. Understanding caching helps troubleshoot why changes don't appear immediately—you may need to clear cache or wait for CDN propagation.

The process of reducing file sizes by removing redundant data, making assets faster to download and cheaper to serve. Image compression can reduce file sizes by 50-80% with minimal visual quality loss using formats like WebP. Framer automatically optimizes images for web delivery while preserving quality where it matters most.

A distributed network of servers that delivers web content from locations geographically closest to each visitor, reducing latency and improving load times. CDNs also provide redundancy and protection against traffic spikes or server failures. Framer hosts all sites on a global CDN automatically for optimal worldwide performance.

The duration from requesting a page to complete rendering, critically affecting user experience and conversion rates. Users expect pages to load in 2-3 seconds; each additional second significantly increases bounce rates. Optimize images, limit scripts, and leverage caching to minimize load time.

The process of fetching and rendering a webpage, measured from request to full interactivity. Page load speed affects user experience, conversion rates, and search rankings. Monitor load performance and optimize bottlenecks regularly.
