What is my LCP on mobile for top landing pages?

I'm trying to understand the performance of my e-commerce website's mobile landing pages and want to dive deep into my Largest Contentful Paint (LCP) metrics. As a site owner, I know page speed is critical for conversion rates, but I'm struggling to accurately measure and interpret my mobile LCP scores. I need a comprehensive strategy to identify, analyze, and improve my mobile page loading performance, especially for my top landing pages that drive the most traffic and potential sales.
