What Is Edge Computing?
Edge computing extends processing beyond the origin server to edge locations distributed globally, close to end users. Unlike traditional CDNs that only cache static assets, edge computing platforms (Cloudflare Workers, Vercel Edge Functions, AWS Lambda@Edge) can execute application code at the edge, enabling dynamic personalization, A/B testing, and API responses with minimal latency.
Why Edge Computing Matters for SEO
Edge computing enables dynamic content with CDN-like performance. You can serve personalized, server-rendered pages from edge locations worldwide, achieving fast TTFB and good Core Web Vitals scores regardless of the user's location. This is especially valuable for international SEO where users span multiple continents.
How Edge Computing Works
Deploy serverless functions to an edge platform. These functions run in data centers near users, handling requests without routing to a distant origin server. Use cases for SEO include dynamic rendering for bots, geolocation-based content, A/B testing, and real-time redirect management.
