Understanding Website Performance with Core Web Vitals
Chief Growth Officer
Consider the crucial components that go into a racing car to ensure optimum
performance, such as the engine, suspension, and various weight and balance
To get the automobile from the starting line to the checkered flag as soon as
possible, each component has a specific function.
We at Reffine believe that vehicle OEMs may and ought to use a similar strategy
when creating websites.
We'll walk you through three essential metrics that evaluate the effectiveness
of your website in this video.
Largest Contentful Paint keeps track of how long it takes for your website's
biggest content components to load. By calculating the computing power and
broadband speed you'll need to handle this weight, you may construct a more
First Input Delay calculates the amount of time it takes a user to interact with
your website, determining how responsive it is overall and making sure that
users aren't waiting for a page to catch up with them.
To help you assess the likelihood of unintentional clicks, Cumulative Layout
Shift measures how much your website shifts while it loads.
Understanding Website Performance with Core Web Vitals - Video
Think of Largest Contentful Paint like a car’s balance and weight, both of which
are crucial when it comes to performance!
While producers design lightweight versions of their vehicles, they also work
hard to make sure they are well-balanced. For example, engineers aim to build
models with a centrally-located engine or the battery placed very low.
It’s the same with a website. Largest Contentful Paint shows the time that it
takes your page to load its largest content elements. The more you use heavy
objects like animations, videos, and huge images, the heavier your website
becomes and the harder it is to load those elements.
If you want to use this kind of content, then you’ll need more computing power
and broadband speed to handle that weight.
There’s also a huge focus on engine responsiveness for different situations. For
this purpose, rally cars have anti-lag systems while more typical vehicles have
a few smaller turbos or small electric compressors.
For websites, First Input Delay measures how fast you can interact with the
page. It is not only about the raw performance of the site, but also about
reaction times. Of course you need to have a fast site, but responsiveness is
equally important. When a user is clicking on a web page, you want them to enjoy
quick reactions rather than waiting for the desired interaction.
Cumulative Layout Shift
The cumulative Layout Shift is similar to a car’s suspension, which is important
for driving fast and comfortably.
Rally cars in particular need to have great suspensions to stay flat so that
they can handle corners and holes better.
Similarly, your website needs to look extremely smooth. The cumulative Layout
Shift metric shows how much the layout of a page moves when loading. Making it
stable helps the user interact with your website quickly without unexpected
shifts causing accidental clicks.
By perfecting all three Core Web Vitals, you can build a great experience for
your users. Finding the perfect balance takes time and effort, but it’s worth
it. Remember, it’s a rally, not a drag race!
