The lateset Google core update at May 2020 introduced new user experience related signals and Core Web Vitals. Although Core Web Vitals metrics are not new except CLS (Cumulative Layout Shift), it draws the attention of most publishers and website owners.
Some publishers noticed most of the pages are marked as Poor URLs and thinking the traffic changes during May 2020 are caused by these Core Web Vitals metrics. But according to Google, these metrics and signals have not been included in May 2020 update and will be enforced during the next year. So most websites have plenty of time to prepare this major Google ranking change.

There should be no or minimum blocking resources like javascript stop the page rendering.
There should be no or minimum javascript stop user start using the website. The page has to be responsible as soon as possible.
The elements on the page should not be changed and causing the user's wrongly clicking something.
Google also defined the bar to mark a page as Google, Needs improvement or Poor:
Ideally, a web page should be loaded within 2.5s and allow users to interact with the page within 100ms and has no element on the page is changing the location.
