Measuring Your LCP
So, how do you know what your LCP is?
A good place to check your LCP performance is to use the tools provided by Google: Google Search Console, Google Page Insights, and Lighthouse.
You’ll find the Core Web Vitals tab in the left navigation of Google Search Console. Going into this tab will show you an overview of your URLs. From there, it’s easy to see what issues there may be and what adjustments you can make to fix them.
