Google aims to reduce the average mobile web page loading time to 1 second

According to Google Analytics data, the average mobile webpage currently takes at least 7 seconds to load. Google now aims to reduce this time to just 1 second. This target isn't arbitrarily set but is based on research findings from Nielsen Norman Group: if a mobile webpage takes longer than 1 second to load, users are less likely to stay on the page.

Given current technology, loading multiple webpages within a few hundred milliseconds is almost impossible. However, Google believes it is feasible to load the primary content of a mobile webpage within 1 second, with the remaining content loading gradually.

Therefore, Google has today released a new set of rules and tools designed to prioritize the optimization of webpage content loading, thereby improving speed. Below is an overview of these rules:

Server response time

Minimize the number of redirects;

Minimize the number of round trips as much as possible;

Avoid using external JavaScript and CSS on the homepage;

Reserve time for browser layout and rendering (200 ms);

Optimize JavaScript execution and rendering time.
