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
Minify CSS: Minifying CSS files can reduce network payload sizes. [Learn more](https://web.dev/unminified-css/).
Potential savings of 13 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 260 ms
Avoid multiple page redirects: Redirects introduce additional delays before the page can be loaded. [Learn more](https://web.dev/redirects/).
Potential savings of 230 ms
Enable text compression: Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. [Learn more](https://web.dev/uses-text-compression/).
Potential savings of 35 KiB
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 17 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 77 KiB
