How do I fix it?
Time to first byte, or TTFB, is a time measurement used in web development that represents the time it takes for a web browser to receive the initial response from a web server. It can have a significant impact on your overall site speed and user experience.
TTFB is made up of three separate components:
- The time it takes to send the HTTP request
- The time it takes to process the request
- The time it takes for the server to send back the first byte of the response to the browser
Basically, the longer it takes to send a request to the server, process it, and send it back to the user's browser, the longer it takes to display your page to the user.
There are several things that might negatively impact your TTFB score:
- Long Redirect Chain
- Network latency
- Insufficient Server Resources
- High web traffic
- Server configuration and performance
- Dynamic content
- DNS response time
To provide a good user experience, Google recommends that sites should strive to have Time To First Byte of 0.8 seconds or less. The 0.8 to 1.8 seconds range is pretty average, especially for dynamic content. Anything beyond 1.8 seconds usually points to an issue on the server side, especially if the TTFB is high from locations close to the server.
To reduce TTFB and enhance overall website performance, consider these strategies:
- Rely on a fast hosting server
- Use a premium DNS service
- Optimize application code
- Optimize your site's Images
- Implement Caching Layers
- Use a Content Delivery Network (CDN)
- Use Minification and Compression
