Lighthouse audits and Core Web Vitals, with clear fixes for the biggest slowdowns.

What is Performance & Core Web Vitals?

Page speed shapes user experience, conversions and search visibility. Pagelyt measures performance on mobile and desktop using Lighthouse and reports Core Web Vitals: Largest Contentful Paint (LCP), Interaction to Next Paint (INP) and Cumulative Layout Shift (CLS).

Instead of a wall of metrics, Pagelyt ranks what is slowing you down: oversized images, render-blocking scripts, unused code and slow fonts. Each recommendation shows the likely gain, so you fix the biggest problem first.

Questions about performance & core web vitals

What are Core Web Vitals?

Core Web Vitals are Google's user-experience metrics for loading (LCP), responsiveness (INP) and visual stability (CLS).

Why is my mobile score lower than desktop?

Mobile devices have slower processors and networks, so large images and heavy scripts hurt more. Pagelyt shows both so you can target mobile fixes.
