What are core web vitals and should I be worried about them?

Core web vitals are something that you may hear more frequently being talked about with your marketing company. They are important, which the name suggests, as they are a core part of thr website user experience. You can find out how your website performs in relation to core web vitals through the free platform, search console. The core web vitals are split in to three sections, LCP, FID and CLS. We will break these down to look at what they mean.

LCP means largest contentful paint and is based on how long it takes for the largest content element to become visible on the page to the users. This may be an image, a video or a block of text. The longer this takes the worse the score. This is to try and improve user experience and cut down on loading times.

Next is FID which stands for first input delay. This is the time from when a user first interacts with your page (when they clicked a link or on a button, and so on) to the time when the browser responds to that interaction. Again the longer this takes, to worse the score.

And finally CLS, which stands for Cumulative layout shift. This basically measures how many movements of elements there are on the page that shift. This can make it hard for the user to click where they need to if the content keeps moving up and down for example.
