SEO: What Are Core Web Vitals?

The Page Experience Update was rolled out starting mid-June 2021 and completed in August 2021. Just like its name, the update is to gauge the page experience by actual users. The page experience update comprises 4 ranking signals: Core Web Vitals, Mobile-Friendliness, HTTPS Security and Absence of Intrusive Interstitials. What are Google’s Core Web Vitals? Let’s talk about what are the three core web vitals elements alongside the core web vitals scores and how we can optimize them. The page experience score consists of 3 Core Web Vitals metrics: the LCP, FID and CLS.

Are Core Web Vitals Important?

The better your core web vitals metrics are, the better your page experience scores will be. In fact, Core Web Vitals are now one of the ranking factors when it comes to Search Engine Optimisation. You would be surprised how optimizing your core web vitals metrics gives a much needed organic boost to your website. In fact, many SEO companies in Malaysia have started to pay proper attention towards this.

1. LCP (Largest Contentful Paint)

-Largest contentful paint is the time taken to load the page’s main content, which can be the largest image or text block on the page. Considered to be a more user-centric metric as compared to the First Contentful Paint, which captures the page speed to load the first element of the page. The main content is what users want to see and what users interact with. A good largest contentful paint takes only 2.5 seconds or less which can be challenging for large web pages or if your web page comes with complicated features. 

To know your page speed score using your LCP data is to gauge your user interactions while browsing your webpage which directly goes into the Chrome User Experience Report. Something that we’ve learned is that using “lazy loading” makes loading speed faster. You should consider upgrading your web house to quicken loading speed.

2. FID (First Input Delay)

-First input delay is the time taken for the browser to process the first interaction by the user on the login page or to put simply the initial page load. For example, when a user lands on a web page and clicks on a video to play it, the first input delay is the time taken by the browser to respond to that interaction, which is to play the video. The first input delay measures only the first interaction done by the user input on the web page, any subsequent interaction won’t be counted. A good first input delay takes only 100ms or less.

If your page consists largely of a blog post from a specific topic, first input delay shouldn’t be your concern in terms of the core web vital but it should be if your page is made of media (images, video etc) then watch out for it.

3. CLS (Cumulative Layout Shift)

-Cumulative layout shift is the measurement of how often users experience unexpected layout changes while waiting for the page load. For example, a user wants to click on a video on the web page, but suddenly the video and the entire page moves downwards and the user ends up clicking on the text above it – this is known as unexpected layout shifts. With new User Interface elements, the cumulative layout shift might change as well.

A good cumulative layout shift score is 0.1 or less. When you are aware of the cumulative layout shift, the user’s browser will be updated on exactly how much space the elements will be used up on the page. Tell you what, here’s a small tip from us, to minimize cumulative layout shift, try using a set size attribute dimensions for all your available media which stabilizes the page elements.
