First let’s define a good user experience. Think about your own interactions with websites when you are looking for information or looking to make a purchase. If there is something that really annoys you – do not have it on your website! For example, I hate it when I click on a link or button, the website shifts, and I actually click on an ad. That is a poor user experience.
Furthermore when a user of your website has a bad experience they will leave and not come back. You have lost that sale. Users have different ideas defining what they will consider a bad experience. Some say load time needs to be fast – they will not wait for a site to display. In addition, others are willing to wait a bit, but if they see a pop-up right away they will leave. Likewise other people are good with the wait time and pop-ups but find a busy site too hard to use.
How does Google define UX?
Since users have a wide variety of markers for user experience, Google has broken it down for us. Here are the 3 main sections that Google is going to be grading.
LCP – Largest Contentful Paint – Is the time it takes for the largest item on your website that will be in the initial viewport (without scrolling) to show.
FID – First Input Delay – This measures the delay that happens when someone interacts with your website.
CLS – Cumulative Layout Shift – The visual shift that happens when websites load.
