Different Types of Core Web Vitals

There are multiple types of core web vitals.

1. Largest Contentful Paint (LCP)

According to the display time of the most substantial blocks visible to an audience, website owners may use the Core Web Vitals metric Largest Contentful Paint to evaluate user experience and determine if a user will find a page helpful.

For users to have a positive experience, website owners must ensure that their pages load quickly. A website that loads quickly not only provides a better user experience but also increases the likelihood of the page ranking higher in Google. Furthermore, compared to a page with poor loading times, quick load times have been demonstrated to affect engagement and conversion rates.

What does LCP Calculate?

LCP basically measures the time a website takes to load different contents within the user browser. It only shows the timing of the different content sections on the visitor’s device.

  • Pictures
  • Preview images for videos
  • Images used as backgrounds
  • Text placed within blocks or paragraphs

2. Cumulative Layout Shift (CLS)

To increase sales and conversions, website owners should make it as simple as possible for users to interact with the links and buttons on their pages. The measure known as Cumulative Layout Shift indicates whether buttons or links change after a page loads and indicates how hard it will be for visitors to interact with items on your website after a page is published.

A successful user experience requires both UX and design; if a web page changes elements as the user is reading, the user will grow annoyed. To help website owners increase usability, click-through rates, and online purchases, CLS assists developers in determining if pictures or links change on the page.

What does CLS Calculate?

CLS identifies if elements of a website, like text and buttons, move around while visitors are reading a webpage. It ensures that the content of the store remains stable during the button movement, prevents any confusion, and enhances user experience. These are the key factors:

  • Layout shift
  • Impact fraction
  • Distance fraction

3. First Input Delay (FID)

Online users like pages that are quick to navigate and visually appealing. First Input Delay helps you find sites that can irritate those who visit by measuring input latency, or the amount of time it takes for a web element to react to a user’s input. To provide material to their viewers, newly created websites use a variety of cutting-edge technology and dynamic content widgets.

Although this kind of material might better the way that it is delivered, these improvements may result in lag periods where the user has to wait for their site to process their input.

To increase customer satisfaction and enhance the usability of the entire website, developers should minimize the amount of time users wait for their web browser to react to their input.

What does FID Calculate?

FID measures the website page’s responsiveness to the user’s actions, like clicking on the link or button tab. FID below 100 milliseconds represents a good user experience.

4. Interaction to The Next Paint (INP)

By measuring the response time of each click, touch, and keyboard input that takes place throughout an individual’s visit to a page, the INP metric evaluates a website’s overall reactivity to user actions. Excluding outliers, the final INP number is the most lengthy interaction ever recorded.

Measuring INP involves two ways: field work or lab. Thus, this is how you can measure Webflow’s core web vitals.
