When it comes to website speed, every millisecond counts. While most website owners focus on front-end performance, TTFB—Time to First Byte—is the server-side metric that can silently ruin your site’s performance and SEO.
Whether you’re on shared hosting or cloud infrastructure, reducing TTFB should be a top priority in 2025. In this guide, we’ll show you how to measure, understand, and improve TTFB using practical methods and AI-assisted tools, plus recommend hosting platforms that keep your site blazing fast.
🚀 What is TTFB?
Time to First Byte (TTFB) measures the time between a browser’s request and the first byte of the response from the server. It includes:
- DNS lookup
- TCP connection & TLS negotiation
- Server processing time
- Response transmission
👉 A good TTFB is generally considered under 200 ms, while anything over 600 ms is problematic for SEO and Core Web Vitals.
