User experience (UX) is a crucial component of every website aspiring to become its visitors’ favorite stop over the internet by providing a smooth browsing experience. The search engine utilizes user experience as the foundational parameter to determine the scoring of SEO signals associated with the website.

How Do We Analyze The Performance of a Website?

The performance of a website is measured by the amount of business it brings to its owners, which is an implicit process. It starts by getting good ranks in search engine results. The search engine uses its algorithms to define which website needs to be ranked at what place. And again, it goes back to analyzing how well your website’s user experience is. We can say that it is all connected and nothing can be missed out if you seek prolific outcomes in a short span of time.

There are plenty of resources you can utilize to understand the performance of your website. The most fundamental tools have been discussed in the later sections. The results in those resources comprise insights of several parameters that tell you the number of things altogether. These parameters that indicate a particular characteristic of your website’s user experience are called metrics.

Core Web Vitals are the significant part of these metrics that help the search engine define your website’s ranks. The best thing is that you can check your website’s performance and your competitors’.

How Do We Extract Data on User Experience Metrics?

Before we know how we get this data, we need to understand the main user experience metrics that define the website’s performance becoming the SEO signals.

The user experience or user-centric data is divided into two categories, field data and lab test data.

Field data or Real User Metrics data is collected from real users over months. It demonstrates the experience of users visiting your website. It is the fundamental indication utilized for defining search rankings.

Lab test data is extracted from the test settings in your browser and used to analyze what your users might see. It helps website handlers to make productive changes in the interests of those expecting business from it.

The performance of the website which can also be reviewed by a collection of field and lab data focuses on a few important parameters as mentioned below;

What Are the Types of Core Web Vitals?

Core Web Vitals are the subset of Web Vitals. Web Vitals are the SEO signals coined by Google to analyze the performance of web pages based on metrics. The Core Web Vitals are applied as user-centric SEO signals to all web pages and indicate the experience of users visiting these websites through reports.

The search engine adopts three Core Web Vitals to measure the performance of your site.

Largest Contentful Paint (LCP)

LCP measures the time taken in rendering the largest content block or element that might consist of images that include background image loaded through URL() function, texts, or blocks when the web page loads. If it is less than 2.5 seconds, you have a good LCP. When LCP is more than the threshold time, it requires website owners to work on the required improvements.

First Input Delay (FID)

FID is a metric to identify the interactivity of web pages. Suppose you have ever come across a website where you face issues performing an event because the button or tab does not respond to you timely and proactively. It is often misunderstood as the time in the interaction of task thread to event handlers. However, the delay occurred between the user’s first interaction with the page and its response. An ideal FID score will range from 100 milliseconds to less than that.

Cumulative Layout Shift (CLS)

CLS represents the visual stability of elements existing on your web page. For example, you visit a page, and when you scroll down, some of its elements, such as navigation bar, images, or even video, are moving unprecedently. CLS is calculated by the product of impact and distance fractions. An ideal range of CLS is from 0.1 to less than that.

The abovementioned are the three Core Web Vitals that you may see while reviewing the report of your website. The more ideal your page’s LCP, FID, and CLS are, the more good results it can bring to you.

FCP is often misunderstood as one of the core web vitals, which it is not. It is a non-core web vital metric that measures the time taken in loading the page to rendering the first-page element such as text, image, or non-white element. An ideal range for FCP is from 1000 ms to less than that.
