loading time
In short and in plain language
Loading time is how long a page takes to be ready. Then you can see and use it in the browser.
Big images, a lot of scripts and slow servers make it longer.
Short times keep people on the page, most of all on a phone.
Search tools look at it too.
Definition
Loading time is how long a page takes until it is visible and usable in the browser. Large images, many scripts and slow servers make it longer. Short loading times keep visitors on the page, especially on mobile, and are taken into account by search engines.
