Cloudflare
Overview
What Cloudflare is
Cloudflare is a connectivity cloud that routes your website's traffic through its worldwide network of data centers. Acting as a reverse proxy, it caches content close to visitors for speed, filters out malicious requests, and manages DNS. The same network powers security products, performance tools, and a platform for running code at the edge.
Core services
Cloudflare's building blocks include a content delivery network, DDoS mitigation, a web application firewall, SSL certificates, and authoritative DNS. Developer products like Workers, Pages, R2 storage, and D1 let teams host sites and run serverless code across hundreds of locations. Many features are usable on a generous free plan, which is part of Cloudflare's wide adoption.
Why it matters
For most sites, Cloudflare improves load times, absorbs traffic spikes, and blocks attacks with a change to DNS settings—no code required. In technical SEO and web development projects, our team uses Cloudflare for faster Core Web Vitals, edge caching, and reliable uptime. For GEO and AEO work, edge delivery helps answer engines and crawlers reach content quickly.

FAQ
Cloudflare — common questions
Is Cloudflare free?
Cloudflare offers a free plan that includes its CDN, DDoS protection, DNS, and SSL for unlimited sites—enough for many small and midsize websites. Paid plans (Pro, Business, Enterprise) add advanced security, analytics, and support.
Is Cloudflare a hosting provider?
Traditionally no—Cloudflare sits in front of your existing host as a CDN and security layer. However, products like Cloudflare Pages and Workers now let you host static sites and run serverless applications directly on its network.
Does Cloudflare help SEO?
Indirectly, yes. Faster load times, better Core Web Vitals, and higher uptime are ranking and user-experience factors. Cloudflare doesn't change your content, but the speed and reliability it adds support technical SEO.
