Time To First Byte (TTFB) is a crucial metric that measures how long it takes for a user’s browser to receive the very first byte of data from a web server after making a request. It is often seen as an indicator of a website’s responsiveness and overall performance.
- What Does TTFB Measure?
It includes the entire process starting from the browser sending a request, the server processing that request, and the server sending back the initial part of the webpage data. TTFB captures network delays, server processing time, and the initial data transfer. - Why Is TTFB Important?
Faster TTFB leads to quicker page loading, better user experience, and improved search engine rankings. A slow TTFB can result in higher bounce rates and reduced user engagement. - Factors Affecting TTFB:
- DNS lookup and network connection time.
- Server processing time, including database queries and application logic.
- Network latency when sending data back to the user’s browser.
- DNS lookup and network connection time.
- How to Improve TTFB:
- Use reliable and fast hosting services.
- Implement caching strategies to reduce server workload.
- Optimize server-side code and database queries.
- Use Content Delivery Networks (CDNs) to serve content closer to users.
- Monitor and manage server load to prevent bottlenecks.
- Use reliable and fast hosting services.
