What are Core Web Vitals and why do they matter
When talking about Core Web Vitals, there are three factors you have to keep in mind. Largest Contentful Paint (LCP) indicates the amount of time it takes for a page to load from a user’s perspective. First Input Delay (FID) indicates the speed with which your audience can begin to interact and use the page. Finally, Cumulative Layout Shift (CLS) quantifies the stability of the page during the loading process.
Nailing these three points obviously has a major impact on the user experience. Imagine you try to load a page, only to be stuck waiting for the content you’re trying to read. And once the page fully loads, you either can’t click on anything or the layout shifts unpredictably. Would you stick around or go elsewhere in search of a better option?
Naturally, you wouldn’t stay on a page with such performance issues for long. And you’re not alone. A recent study has shown that 53% of online shoppers expect e-commerce pages to load in three seconds or less. So, if your page is loading too slowly or difficult to interact with, you’ll quickly bleed consumers. In fact, in the same survey, 21% of consumers indicated that slow loading times represents their main point of frustration during the online shopping experience.
So, if your business wants to attract and retain customers, it’s essential to maintain high Core Web Vitals. Otherwise you not only risk driving away your audience but leaving behind a negative impression.
