Google algorithm updates happen throughout the year. Keeping up with these updates is a tough task for any organization. The aim of Google is to provide its users with the most authentic and reliable information. For this, it has many ranking criteria, and page Experience Signals is an important one among them. Further, some of the signals that are prominent in this category are mobile friendliness, page load speed, user-friendly pages etc.

Google aims to measure the quality of experience a user gains from the website. It ranks those websites with great user experience higher in the search results through core web vitals.

So, let’s understand core web vitals in detail.

What exactly are Core Web Vitals?

Core Web Vitals check involves three important metrics that defines the user’s experience when a page loads. It covers many factors including how fast the content loads, how fast the browser responds to an input from the user. Moreover, it also measures the stability of the content when it loads the browser.

Here are the three elements that core web vitals consist of:

● Largest Contentful Paint (LCP)

This measures the speed taken for the main content of a page to load. Google prefers fast loading and gives higher ratings to those pages where the main content loads within 2.5 seconds of a user landing on the page. Further, the main content is often the largest image or text block. So, it is advised to optimize the loading time of large images or videos in your web page.

● Cumulative Layout Shift (CLS)

Using this element, Google measures how often a user experiences unexpected shifts in the layout when they are on the page. Many times, shifting the page elements or even the entire layout will negatively impact the user experience. Further, Google considers this as a negative user experience and aims to get such distractions minimized in the websites. For a page to have a good CLS it should be less than 0.1.

● First Input Delay (FID)

This refers to the time a page requires for becoming interactive. Usually a visitor expects the page to become interactive as soon as the first visual element such as image, button, or scroll bar loads on the page. However, there is always a delay in the loading of the first element. It takes time for the page to respond to our actions. Moreover, users get frustrated when this happens and a good user experience translates to minimum FID. The optimal measurement of FID is 100ms.
