What is a CDN?
A CDN (content delivery network) is a network of servers distributed across many locations that caches and delivers your site’s static content — images, CSS, JavaScript and sometimes full pages — from the server closest to each visitor. This drastically reduces latency for global audiences.
Why CDNs matter for SEO
Page speed is a direct ranking factor and a core part of Core Web Vitals. A CDN lowers time to first byte, improves largest contentful paint and keeps load times consistent worldwide. Faster pages also convert better, reducing bounce rate.
Key benefits
- Faster global page loads and lower latency.
- Protection against traffic spikes and DDoS attacks.
- Reduced load on your origin server.
- Built-in caching that eases server pressure.
CDN and GEO
AI engines and crawlers prioritize accessible, fast content. A responsive site with a CDN is crawled more efficiently, which helps both indexation and the consistent delivery of content that AI systems consume.
