Google Web Vitals: What’s changing for SEO?

[kumartk]

Behind the English terms lie approaches that are not only easy to understand but also extremely valuable for users. Are you familiar with the phenomenon of just about to click a button, but at that moment the entire page shifts, taking you somewhere completely different? Then you'll love CLS.

LCP: Largest Contentful Paint or “Loading”
This first criterion describes how long it takes until the largest element that needs to be loaded on the current page is fully visible – above the fold, i.e. in the area that users actually see when they first visit the page.

In addition to the fact that Google considers this loading time for ranking purposes, el salvador phone number data this criterion also has a very practical use: If visitors have to wait too long to see something above the fold, they'll leave very quickly. It's rightly a feature worth considering.

By the way, this is measured in seconds: Google is satisfied with a loading time of less than 2.5 seconds, 2.5-4.0 seconds is something that needs improvement, and it should not be more than 4.0 seconds.


FID: First Input Delay or “Interactivity”
Using this second criterion, Google measures how much time passes between a user request and the browser's response: For example, how long does it take for the browser to respond after clicking on a button and then display the desired request?

Here, too, delays quickly lead to user frustration, which is why this criterion also makes sense. It's measured in milliseconds: Up to 100 milliseconds makes Google happy, 200–300 milliseconds offer room for improvement, and anything above that is considered too slow.



CLS: Cumulative Layout Shift or “Visual Stability”
This is the "everything shifts" criterion. For content like images or graphics that take a little longer to load, the browser doesn't reserve space when rendering the page. Therefore, users may have already started reading and clicked a button, but at that very moment, an image higher up loads completely, taking up space and forcing the rest of the page to shift down.

This leads to misclicks and is very annoying for users. A good reason to include this criterion in Google Web Vitals.
