How Core Web Vitals Affects eCommerce Websites – 2021

Core Web Vitals for eCommerce Websites

The Core Web Vitals of an eCommerce can be the key to guarantee a good SEO positioning and an optimal user experience. And Google has announced a new update that arrived in June 2021 and that will take into account different metrics to evaluate and determine the browsing experience on web pages. 

These are metrics that will become key factors in determining the positioning of websites in the first pages of the search engine. We already know that e-commerce has become a solution adopted by a significant number of businesses today, so it is imperative to ensure that the user experience is as positive as possible.

What are Core Web Vitals?

They are the set of metrics that Google uses to evaluate the browsing experience of a user on a web page. These metrics analyze different factors, such as the page load time, the quality of the website, or the relevance of its content. All these factors, if they are managed perfectly, will favor the positioning of the pages in the search engine.

For businesses that operate online, it is very important to be familiar with these metrics, since to improve the SEO of a page it will be necessary to manage the Core Web Vitals perfectly and make the changes that are necessary to improve the browsing experience of the users. 

These are the three metrics that we must know and master. Core Web Vitals are the set of metrics that Google uses to evaluate a user’s browsing experience on a web page.

Largest Contentful Paint (LCP)

Largest Contentful Paint metric measures the loading speed of the content of a web page, from the beginning until the different elements appear, whether they are only texts such as videos and images. For a web page to pass this parameter, its loading time must be less than 2.5 seconds.

First Input Delay (FID)

First Input Delay second metric measures the time a user must wait until they can interact with the web page. Therefore, the difference between LCP and FID is that the first parameter measures the time that must pass until the user can view the elements, while the second measures the time that must pass until the user can click on any of the elements. elements on the page to get a response. A good FID should be less than 100 milliseconds.

Cumulative Layout Shift (CLS)

Lastly, the Cumulative Layout Shift measures visual stability. This refers to the frequency with which visual content unexpectedly changes sites during the loading process of a web page. The CLS is measured by the number of times this happens, and it should be below 0.1.

The Weight Of Each Metric in Lighthouse

The launch of the Core Web Vitals has coincided with the arrival of the sixth version of Lighthouse. Lighthouse v6 distributes the metrics from highest to lowest as follows:

Lighthouse v6.0 MetricsWeight
First Contentful Paint (FCP)10%
Speed Index (SI)10%
Largest Contenful Paint (LCP)25%
Total Blocking Time (TBT)30%
Time to Interactive (TTI)10%
Cumulative Layout Shift (CLS)15%

As you can see in the list, the greatest weight is the TTB (Total Blocking Time), then the time to wait until the necessary resources are loaded and the previously mentioned LCP.

The CLS, however, has a fairly small impact and the FID does not currently participate among these Lighthouse metrics because to calculate it, it is necessary to have a real user since it cannot be carried out with a load simulation.

These metrics are variable since it is most likely that in future versions of Lighthouse they will change as the previous versions did.

How do they affect your eCommerce?

These parameters are important because they help determine how good the user experience is when browsing a web page according to Google. Therefore, ensuring that the results of these parameters are correct will help to improve SEO positioning and, as a consequence, it will be easier for users to find the web page in question. These Core Web Vitals, therefore, affect different aspects, which we will talk about below.

SEO (Search Engine Optimization)

Initially, these parameters or metrics were introduced as recommended measures to improve the SEO positioning of web pages. However, from the year 2021, the Core Web Vitals will become essential elements to improve the SEO ranking of an online store. In addition, these are metrics that allow us to evaluate the interaction with a page or online store, and this allows us to ensure that the user experience is as optimal as possible.

UX (User Experience)

The user experience is, therefore, another aspect that Core Web Vitals help to improve and optimize. By being metrics that measure the speed and waiting time of users, online stores can ensure that their customers will get a fast and efficient response and a quality browsing experience.

Accessibility and Navigation

As we have mentioned, the user experience is closely related to the accessibility of the website and the browsing process. The Core Web Vitals of an eCommerce allow you to analyze how the user navigation process is on a page; they also make sure that the page is accessible in a very short time. Remember that most users leave a web page if it does not load in a few seconds.

To guarantee the success of an eCommerce the user experience must be optimal from the first click to the last.
