Pagespeed analysis

OVERALL SITE SPEED: AVERAGE (details below)

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

Defer offscreen images: Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. [Learn more](https://web.dev/offscreen-images/).
Potential savings of 403 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](https://web.dev/render-blocking-resources/).
Potential savings of 6,540 ms

Remove unused CSS: Remove dead rules from stylesheets and defer the loading of CSS not used for above-the-fold content to reduce unnecessary bytes consumed by network activity. [Learn more](https://web.dev/unused-css-rules/).
Potential savings of 265 KiB

Efficiently encode images: Optimized images load faster and consume less cellular data. [Learn more](https://web.dev/uses-optimized-images/).
Potential savings of 26 KiB

Minify CSS: Minifying CSS files can reduce network payload sizes. [Learn more](https://web.dev/unminified-css/).
Potential savings of 33 KiB

Remove unused JavaScript: Remove unused JavaScript to reduce bytes consumed by network activity. [Learn more](https://web.dev/unused-javascript/).
Potential savings of 140 KiB

Avoid serving legacy JavaScript to modern browsers: Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren’t necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers. [Learn More](https://philipwalton.com/articles/deploying-es2015-code-in-production-today/)
Potential savings of 7 KiB

Properly size images: Serve images that are appropriately-sized to save cellular data and improve load time. [Learn more](https://web.dev/uses-responsive-images/).
Potential savings of 334 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](https://web.dev/uses-webp-images/).
Potential savings of 390 KiB
