Google's Core Web Vitals have been causing a stir in the SEO world since June 2021. They include signals for the user-friendliness of websites in their rankings. Conversely, this means that metrics such as mobile optimisation as well as website speed and low-disturbance loading times lead to higher rankings in Google Search. This also includes the need to optimise websites for different browsers.

The Core Web Vitals therefore refer to the technical aspects of search engine optimisation. However, just doing technical SEO is no longer enough. The Google ranking factors of the Core Web Vitals revolve around three areas of user experience:

Largest Contentful Paint (LCP)First Input Delay (FID)Cumulative Layout Shift (CLS).

User Experience Factors - What do the three metrics LCP, FID and CLS mean in detail?

Largest Contentful Paint (LCP) - Load Time

The LCP measures the loading time of the largest element in the visible area of the website. If this takes a long time, many users abort before they have even reached the page. According to Google, this rendering time should be under 2.5 seconds. If it takes longer, up to 4 seconds, this value is considered to be in need of improvement.The loading time should not be even longer.

First Input Delay (FID) - Interactivity

The First Input Delay describes the interactivity of the user with the page.Google records the time from the first activity of the user to the reaction of the browser.The faster, the higher the "retention rate" among users, so the best is when the web pages load faster.The value should at best be below 100 milliseconds. Anything above that is considered to be in need of improvement.

Cumulative Layout Shift (CLS) - Visual Stability

The CLS captures the layout elements of the website that shift unexpectedly.This does not include planned animations or whether the website is too slow. This only includes the erroneous shifts, such as when a button slides down because the text loads late or a banner tears the content apart.
