Why do FCP and LCP matter?

Faster FCP

First contentful paint (FCP) is how quickly the first image or text is displayed on screen.

Once someone sees content appearing, they are reassured the page is loading successfully.

Quicker LCP

Largest contentful paint (LCP) is when the biggest piece of content is displayed.

It gives the page a fast loading feel. As a result, a visitor is less likely to navigate away from the page.

A one-second delay in loading times can reduce conversion rates by 20%


Optimize CSS Loading

Generate optimized styles for every page, greatly increasing speed, especially on mobile.

Defer Non-Essential Javascript

Delay some tasks until after the page loads, so the important stuff loads faster.

Lazy Image Loading

Only loads images the user can see, making your site faster and saving bandwidth for your host and customers.

Image Guide

Discover and fix images with a suboptimal resolution, aspect ratio, or file size, improving user experience and page speed.
