What is Time To First Byte (TTFB)?
TTFB measures the time it takes for a web browser to receive the first byte of the response from your web server.
This measure is a good indicator for the repsonsiveness of your website to the visitors.
A responsive website will provide better user experience and improve your Search Engine Ranking as Google takes into account of the TTFB of a website in their algorithm.
