Time To First Byte (TTFB) is important for web marketers because there’s a statistically significant correlation between a fast TTFB and a high ranking on Google for generic search terms (e.g. those not including your brand name). Here's a beginners guide to how it's measured, how you can check yours and what qualifies as a good Time To First Byte (TTFB).
Time to First Byte (typically abbreviated to TTFB) is the measurement of time it takes for the initial computer handshake between your browser (Chrome, Firefox, Safari, etc) and the website you're visiting.
Time to First Byte (TTFB) is the measurement of time between:
Someone typing in your web address into their web browser and hitting “Enter”
The moment that your website replies with “I’m alive”
Time To First Byte isn't about how long it takes your entire webpage to download, nor is it a measure of how quickly all the pictures load. It's just about that initial connection; and it's that which is important.
