Understanding China's Internet Landscape in 2025

Before diving into optimization techniques, it's crucial to understand the current state of China's internet infrastructure. The Great Firewall (GFW) continues to be a significant factor, but it's not the only challenge. Network latency, domestic routing preferences, and regulatory compliance all play roles in website performance.

The key insight for 2025 is that China's internet has become more sophisticated, with better domestic infrastructure but stricter international gateway controls. This means optimization strategies need to be more nuanced than simply "use a CDN."

12 Proven Steps to Optimize Your Website for China
