Core Web Vitals : A guide on new performance metrics

So every year Google makes necessary changes to its algorithms and we should be well adapted to such changes. Some changes are made to the ranking factors and one such major change is the introduction of Google Core web vitals. So this change is to be introduced somewhere in 2021 and the reason we are well informed early is to take the necessary steps to embrace this change.


So let’s see what exactly we mean by core web vitals …

It is basically associated with the page loading speed, how fast is it interactive and stable. When a group of users visit a page their user experience depends on page loading speed, interactive speed etc. After all, these affect the user’s interest in your site. Core web vitals is related to all these user experiences.


Already Google has configured Page experience signals and now core web vitals joins this group of signals to measure few metrics like mobile-friendliness, HTTPS security, safe browsing, etc. By introducing core web vitals along with page experience signals it encourages site owners to build pages to rank higher. However, this does not mean that even if the content is of no good quality the page will still rank if it has a good user experience. Content relevance is still important and this along with good page experience signals will give a boost to the page and now with google core web vitals also added to this it will give owners an opportunity to rank higher in the search results. When your pages come on Top stories it is kind of a big deal. AMP (Accelerated Mobile Pages) was a criterion for pages to load in Top Stories. But with the launch of google core web vitals, AMP is not going to be a criterion anymore.

Now let’s see move on to some technical concepts


What are the exact signals of Core web vitals and how does it increase the page loading speed.

  1. Largest contentful Paint ( LCP)

Google should recognize the largest image, video, or text in that site and how fast does it take to load. This is LCP. This can be largely influenced by a lot of factors like server time, JavaScript, etc.


2. Cumulative layout shift ( CLS)

This is basically when a page is loaded we click a thing and suddenly there is a layout shift and we hit something else. Which means our page isn’t stable. This signal should be minimally low.


3. First Input delay ( FLP)

As the name suggests how fast it is interactive. When you click something and have to wait for a             long time it is not pleasant user experience. Every user expects a fast interactive web page and that is exactly what we mean by FLP.



Core web vitals is a collection of all these metrics and we have a long way to go to learn more about this and get a hands-on user experience. Let’s wait for the next update from Google meanwhile we brush up our knowledge on Core web vitals.
