What is core web vitals?
In the world of web performance, your website is one resource among many. It’s easy to forget that everything you do on a website, from navigating to reading content and even buying something—has an impact on its load time. That’s why we created this guide: to help you understand what makes up a healthy Core Web Vitals score, so you can make sure yours stays healthy!
Largest Contentful Paint (LCP)
When measuring the user experience of your website, you’ll want to focus on the time from when a page is requested to when the first meaningful paint is received by the user. This is called LCP and it’s used to measure how quickly pages load and what happens in between.
LCP can be improved by reducing the amount of data that needs to be downloaded as part of rendering each page. For example, if you’re using JavaScript libraries or frameworks such as NodeJS or ReactJS (or even just plain old HTML), those libraries themselves might be downloading extra resources like images or stylesheets during their initial load time—and this will add up over time!
First Input Delay (FID)
First Input Delay (FID) is a length of time that the browser takes to load the first page on your site. The FID can be adjusted by changing the HTML code of your page, but we recommend not doing this unless you know what you’re doing.
Cumulative Layout Shift (CLS)
Cumulative Layout Shift (CLS)
Cumulative Layout Shift is a combination of LCP and FID. It measures the time it takes for the browser to render your page, and is measured in milliseconds. CLS is used to measure how long it takes users to load pages on your site, as well as how fast they can move from one page to another on that same site.
These three metrics are used to measure the user experience of your website
These three metrics are used to measure the user experience of your website.
LCP: The time it takes for the first bit of content to be displayed, including text, images and videos.
FID: The time it takes for the first input to be processed by your server (e.g., submitting an email). This includes everything from receiving data via AJAX requests and parsing through it before sending back an HTML page with all its elements laid out properly in order.
CLS: Total time taken by a user from clicking “go” on a link until they reach their destination page—including all loading screens between pages as well as any other delays caused by slow servers or poor coding practices like having too many divs on one page!
How core web vitals affect ranking?
These three metrics are used to measure the user experience of your website. They help you understand how fast the content is being loaded, where it’s coming from and how much time is spent on each page. If a page takes too long or loading times increase significantly, this can affect customer satisfaction levels which means that it won’t be profitable for businesses unless they fix these issues quickly!
