Do you want your website to load fast, engage users better, and rank higher in Google? Then understanding and improving Core Web Vital is a must. Google made it clear: performance and user experience matter. If your site scores low on these vitals, you’ll probably lose rankings—and traffic too. So how do you know if your site is doing well?
There are many tools out there to measure your Core Web Vital. In this blog, I’ll break down the top 5 tools that can help you check and improve your site’s vitals.
What Are Core Web Vitals? (H2)
Before jumping into the tools, let’s quickly understand what Core Web Vital actually are.
Core Web Vitals are a set of performance metrics created by Google to measure user experience. These vitals focus on three key aspects:
- Largest Contentful Paint (LCP) – It measures loading performance. Your page’s main content should load within 2.5 seconds.
- First Input Delay (FID) – It measures interactivity. The page should respond to user input within 100 milliseconds.
- Cumulative Layout Shift (CLS) – It checks visual stability. Layout shifts during load should be minimal.
In 2024, Google is replacing FID with Interaction to Next Paint (INP), so keep that in mind when analyzing your site.
Why Core Web Vitals Matter (H2)
Google made Core Web Vital a ranking factor because they show how good your site feels to users. Faster, more stable sites = better user experience = higher rankings. A bad score may cause high bounce rates and less time on site.
So improving your Core Web Vitals not only boosts SEO but also improves your conversion rate. Whether you run a blog, eCommerce site, or business website, vitals matter.
