As you may or may not be aware, Good old Google usually releases a small number of core updates per year, along with hundreds of smaller tweaks to its algorithms. These may be related to how the site appears in search results or the importance of specific offerings that Google offer (Google My Business, for example). As part of their commitment to a good Page Experience, Google has shifted their focus and segmented this experience into what they are calling Core Web Vitals.
Core Web Vitals (we'll abbreviate this to CWV from now on) is the new standard of quantifying the experience of your site and identifying opportunities to improve. These don’t include the other web vitals that they would hope all sites have (valid SSL’s, mobile-friendly sites etc), but CWV is made up of three specific page speed and user interaction measurements: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). These are measured on a 'Good', 'Needs Improvement' and 'Poor' scale, depending on the individual website's score.
As far as we know, poor results in vitals won’t penalise you, but if competitors have better results there is a very real chance they will rise up the ranks, thus dropping yours down. It is important to remember that any update to the search algorithm could have a positive or negative impact on your website, but this one is causing much concern in the industry - it could be huge.
There is also no ‘one size fits all’ approach to fixing a site, as there are so many variables in play on any given site.
