Pagespeed analysis


CUMULATIVE LAYOUT SHIFT SCORE: AVERAGE. Have you ever been reading an article online when something suddenly changes on the page? Without warning, the text moves, and you’ve lost your place. Or even worse: you’re about to tap a link or a button, but in the instant before your finger lands, BOOM – the link moves, and you end up clicking something else! This is a measure of how often this is happening on your website.

FIRST CONTENTFUL PAINT MS SCORE: AVERAGE. This measures the time taken for the first thing on your website to load when a visitor goes there.

FIRST INPUT DELAY MS SCORE: AVERAGE. How long it takes for your website to react if the user interacts with it in some way, such as clicking a link or button.

LARGEST CONTENTFUL PAINT MS SCORE: AVERAGE. Measures how long the main part of the website takes to load.

Opportunities for improvement

Efficiently encode images: Optimized images load faster and consume less cellular data. [Learn more](
Potential savings of 81 KiB

Eliminate render-blocking resources: Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. [Learn more](
Potential savings of 500 ms

Properly size images: Serve images that are appropriately-sized to save cellular data and improve load time. [Learn more](
Potential savings of 491 KiB

Serve images in next-gen formats: Image formats like JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG, which means faster downloads and less data consumption. [Learn more](
Potential savings of 469 KiB
