Page Speed Checker

TTFB is the time between requesting a page and receiving the first byte of the response. It mostly reflects your server, hosting, database and caching. Under 400 milliseconds is great, and over one second usually means your server needs caching, an upgrade or a CDN.

Google uses page experience signals, including Core Web Vitals, as part of its ranking systems. More importantly, slow pages lose visitors: people leave when a page takes more than a few seconds to show content, which hurts sales and engagement.

Speed depends on where and how it is measured. This tool measures from our server with a single request, focusing on server response and page structure. Browser based tools also render the page and measure visual metrics on a simulated phone. Use both for a complete picture.

These are JavaScript files that the browser must download and run before it can show the page. Adding the defer or async attribute to scripts that are not needed immediately lets the page appear faster.

Enable caching and compression, use a good host or CDN, compress images and serve them in WebP, lazy load images below the fold, remove unused plugins and scripts, and defer non critical JavaScript. Our Image Compressor can help with the images.
