Core Web Vitals Explained

You may not yet know what Core Web Vitals even means. That’s fair; after all, it’s only just starting to be spoken about regarding SEO.

The Core Web Vitals refers to, as you could probably guess, some core factors that help with ranking a website.

They are mainly to do with the reactivity of a page when you click on something, the loading speed of elements, and the layout’s stability.

We’ll go over each of these towards the end, but for now, you should think about how you can prepare for these changes.

What You Should Think About Now

Earlier this year, Google announced that Core Web Vitals would officially become a ranking factor in May 2021. For you, as a website owner, that means several things.

Firstly, if your website has a few graphics and elements, and they can take time to load, Google will start placing its focus on the loading time of the most significant graphic element; this will be known as the LCP.

The LCP stands for largest contentful paint. Previously, the loading time for the first elements to appear was the most important, but that’s about to change. Generally speaking, Google ranks these into three different categories.

Secondly, we have the FID, otherwise known as the first input delay. As touched upon earlier, this refers to how interactive a page is in terms of when something is clicked upon. Google ranks this quicker than the LCP.

Lastly, in terms of Core Web Vitals, we have the CLS cumulative layout shift. This jolly sounding name refers to the visual stability measurement of the site. Complicated sites will stagger the loading of different sections of content, altering the end view. CLS basically means the time it takes for all elements to move in their final place.
