Core Web Vitals: What you need to know about the new Google update

March 30, 2021

In May 2021, Google will definitely roll out the Page Experience Update, which was already announced last year. The main focus is on the Core Web Vitals. These will have a stronger influence on the ranking of websites from May 2021. But what does this mean for you?

Focus on 3 key figures

With this update, Google is once again taking a step further in the direction of user experience. The Core Web Vitals now act as ranking-relevant factors to make the usability of websites measurable. These Core Web Vitals are composed as follows:

  • LCP: Largest Contentful Paint (loading time).

How long does it take for a page to load completely?

  • FID: First Input Delay (Interactivity)

How long does it take for the website to respond to user input?

  • CLS: Cumulate Layout Shift (Visual Consistency)

Do elements on the web page stay in a fixed location or do they shift along with usage?


Effect of the update

The impact of the update will not pick up immediately overnight. Rather, the three factors will gain relevance over a longer-term period, as was already the case with the "mobile friendliness" factor. It remains questionable, however, what weight will be given to these three factors. If the loading time becomes an effective ranking factor, websites that allow banner advertising will be disadvantaged. However, these are among Google's biggest customers and financial backers. Whether the major corporation can afford to step on the toes of its own partners remains to be seen. One thing is certain, however: Google's update highlights the ever-increasing importance of user experience issues - and for the first time provides website admins with detailed documentation on how to optimize this user experience. We are happy to support you in the implementation.
