Core Web Vitals: Get Ready for the Next Official Google Ranking Factor

Yet another Google ranking factor is about to roll in. And guess what? Like always, web developers and SEO experts are already in pain. Finding it hard to get their head around.
How does this new official ranking factor work? How is it gonna affect website rank? What can one do to maintain or improve their website rank once Core Web Vitals are in place?
So many questions. Essential to be answered for your website.
Just like you, we are also trying to understand the concepts of Web Vitals. So we thought it might be helpful to share what we have learned so far.
In this article, we will walk you through the details of Core Web Vitals. Let’s see if we can find answers together.

A basic concept on Core Web Vitals- The Three Signals

Core Web Vitals are the new Google ranking factor based on user experience.
The search engine giant – Google took this initiative while keeping in mind to serve a great user experience on the internet.
This is surely gonna be the next big element to affect websites’ rank on search results.
The unified guidance intends to ease the process of understanding UX metrics. Now you only have to focus on certain metrics, known as Core Web Vitals.
In the first half of 2020, Google made it public that, Web Vitals is going to be the next official ranking factor.
Since then, three main specifics have been in talks among SEO experts and website owners. Page Loading Speed, Content Interactivity, and Visual Stability.
Technically, LCP, FID, and CLS are those three metrics, collectively named as Core Web Vitals.

Largest Contentful Paint (LCP)

Your first chance to deliver a good on-page experience is providing a faster loading speed. People don’t like sites that take ages to load.
Largest Contentful Paint (LCP) is the standard that measures sites’ loading performance. This metric measures the time a page takes to load its main contents while rendering the largest elements.
When above-the-fold contents become visible on the viewport, the largest elements take more time than other main elements.
Thus, to measure page load speed, it’s highly effective to calculate the time it takes to download the largest elements on a web browser.
Contents like images, videos, SVG, and background images loaded through the ‘url()’ function are considered as the largest contents.

Standard LCP Score

To Google’s standard, if your site loads in less than 2.5 seconds, that’s great. You might need to make improvements if it’s between 2.5 to 4.0 seconds.
But, taking more time than that? You really need to work on it and improve its loading performance if it’s more than 4.0 seconds.

What causes a poor LCP score?

Ways to Solve those issues

You have several ways to solve the loading time issue to improve LCP score. But you have to first identify what causes your website loading slow?
If you are facing a slow server response time, you can try using a nearby Content Delivery Network (CDN). Also can try to do Server-Side Caching or can establish early third-party connections.
When render blocking time is causing the problem, try to compress CSS & JavaScript files, remove unnecessary scripts, and try to optimize your codes.
You can also optimize large files like images, compress text files, preload essential resources and server side rendering.

First Input Delay (FID)

This metric measures interactivity of web pages. An interactive website or webpage involves users more and increases site engagement.
FID measures the response time when a user interacts with a section like a call to action button, link, or a custom JS feature.
For example, a user taps on a button that is supposed to show a popup on-click. The metric will measure the time the web page takes to show the popup on-screen after the button is clicked.
So, FID is the delay time between a call made and the action to perform for an interactive section. This delay time or response time is actually the FID score that search engines measure.

Standard FID score

Google considers pages with First Input Delay (FID) of under 100 milliseconds as good. Anything between 100 to 300 mS is considerable. However above 300 milliseconds is labeled as poor.

What causes the delay?

Ways to solve those issues

To reduce the first input delay time, you can try splitting long tasks into smaller ones. Break down large codes and reduce the amount of JavaScript loading on an individual page.
Reduce main thread blocking time by using a web worker. A web worker will move non-UI operations to a different worker thread.
Also, reduce JavaScript execution time by holding off the unused JavaScript and minimizing unused polyfills.

Cumulative Layout Shift (CLS)

The Cumulative Layout Shift (CLS) benchmark is set to ensure a smooth and natural shift of contents. It measures visual stability.
What is actually visual stability? Let’s describe this with an example.
Suppose, someone is reading an article on your site, and all of a sudden a popup shows up. Or, contents start moving, without any warning.
We all know how irritating that is from the user’s point of view. Lack of stability causes enough harm to web performance.
To deliver better visual stability, a smooth and natural shift of contents is essential.
CLS metric quantifies surprising shifts of contents on a page and helps to make sure that the page performance is as satisfying as possible.

Standard FID score

CLS core below 0.1 is good for the site’s stability. A score less than 0.25 is still adequate. But Google considers sites that have higher CLS score than 0.25 as poor for visual stability.

What causes the poor CLS?

What causes the poor CLS?

A great best practice is to define the width and height attribute of images and videos. The web browser allocates specific space for it during page loads.
In terms of responsive web design, you can use CSS aspect ratio. There are some different ways to assign aspect ratios.
Try to allot the size of ads, iframes, and embeds. You can reduce ad slot size, for minimizing layout shifts caused by these elements.
Always avoid dynamically injected contents. The best practice is to avoid inserting unexpected dynamic contents. Only show those contents when a user interacts to see those contents.
