What Is TTFB and Why Does It Matter?

Time to First Byte (TTFB)

   • Faster websites keep users engaged and reduce bounce rates.
2. Better SEO Rankings:
   • Search engines like Google prioritize fast-loading websites.
3. Increased Conversions:
   • Faster load times lead to better user retention and sales.

Tip 3: Use a Content Delivery Network (CDN)

How a CDN Improves TTFB

• A CDN stores copies of your site’s assets on servers worldwide, delivering content from the server closest to the user.

Recommended CDNs

   • Free and paid plans with robust features.
2. KeyCDN:

Tip 5: Minimize External HTTP Requests

Impact of HTTP Requests on TTFB

• Too many external requests (e.g., scripts, fonts) increase server response times.

How to Reduce HTTP Requests

1. Combine CSS and JavaScript Files:
   • Use plugins like Autoptimize to merge files.
2. Host Fonts Locally:
   • Download and serve Google Fonts from your server.
3. Disable Unnecessary Plugins:

2. Log in to your hosting control panel and navigate to the PHP settings.
3. Select the latest stable version (e.g., PHP 8.0 or above).
