What is the time to first byte (TTFB)?
The Time To First Byte measures how long it takes for the first byte of the server to be received by the browser. So in short, how quickly does your server respond to a visitor’s request.
Why is the TTFB so important?
Speed counts on the internet. The faster your server can react to a request from your visitors, the faster data will be sent and the website will be loaded. The TTFB also plays a role in the Core Web Vitals introduced by Google in relation to the loading times of your website. So it is also a ranking factor in the Google search engine.
How can I optimize the TTFB?
The TTFB is mostly server dependent. So unfortunately there is not much you can do. The most obvious thing to do is to switch to a faster provider. You can also try to install a caching tool (e.g. WP Rocket). Using content delivery networks can also be helpful.
