❓ What does it mean?
❓ What is TTFB?
Time to First Byte (TTFB) is the time it takes for a user’s browser to receive the first byte of data from the server after making an HTTP request.
It measures server responsiveness and network latency.
Good TTFB: < 200 ms
Needs improvement: 200–500 ms
Poor TTFB: > 500 ms
🚨 Why is it important for SEO?
🚨 Why TTFB Matters for SEO
Google Ranking Factor: Page speed (including TTFB) influences SEO rankings.
User Experience: A slow TTFB delays page rendering, making the site feel unresponsive.
Crawl Efficiency: Googlebot may crawl fewer pages if the server is slow.
Conversions: Slow-loading sites frustrate users and reduce engagement.
✅ How to Fix It
❌ Example of Poor TTFB
A user clicks on www.example.com/product.
The browser sends a request, but the server is overloaded or not optimized.
It takes 1.2 seconds before the first byte of HTML is received.
Result: Page feels slow, users may abandon, and SEO performance suffers.
❌ Bad Example
✅ Example of Good TTFB
A request is made to www.example.com/product.
The server responds in 100 ms with the first byte of data.
The page begins rendering almost instantly.
Result: Faster load, better SEO and user experience.
✅ Good Example
🛠 How to Improve TTFB
Use a Content Delivery Network (CDN) to serve content closer to users.
Enable server-side caching (e.g., page caching, Redis, Varnish).
Optimize database queries and reduce unnecessary backend processing.
Use modern web servers (e.g., Nginx, HTTP/2, QUIC/HTTP/3).
Minimize use of heavy middleware or redirect chains.
Ensure SSL/TLS handshakes are optimized.
