Serve images in next-gen formats. Potential savings of 6,090 KiB
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.
Efficiently encode images. Potential savings of 5,575 KiB
Optimized images load faster and consume less cellular data. Learn more.
Defer offscreen images. Potential savings of 3,756 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. Learn more.
Preload key requests. Potential savings of 6,030 ms
Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load. Learn more.
Use video formats for animated content. Potential savings of 447 KiB
Large GIFs are inefficient for delivering animated content. Consider using MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF to save network bytes. Learn more
Properly size images. Potential savings of 386 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn more.
Remove unused JavaScript. Potential savings of 129 KiB
Remove unused JavaScript to reduce bytes consumed by network activity. Learn more.
Eliminate render-blocking resources. Potential savings of 590 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. Learn more.
Remove unused CSS. Potential savings of 58 KiB
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.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Reduce the impact of third-party code

Leverage the font-display CSS feature to ensure text is user-visible while webfonts are loading. Learn more.
Avoid enormous network payloads
Total size was 8,404 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn more.
Serve static assets with an efficient cache policy
15 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more.
Avoid an excessive DOM size
2,002 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn more.
Minimize main-thread work
5.4 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn more
Reduce JavaScript execution time
1.5 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn more.
Keep request counts low and transfer sizes small
62 requests • 23,765 KiB
To set budgets for the quantity and size of page resources, add a budget.json file. Learn more.
Avoid long main-thread tasks
13 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay. Learn more
Avoid large layout shifts
5 elements found
These DOM elements contribute most to the CLS of the page.
Largest Contentful Paint element
1 element found
This is the largest contentful element painted within the viewport. Learn More
Avoid chaining critical requests
6 chains found
The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load. Learn more.

Does not use HTTPS
1 insecure request found
All sites should be protected with HTTPS, even ones that don't handle sensitive data. This includes avoiding mixed content, where some resources are loaded over HTTP despite the initial request being servedover HTTPS. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs. Learn more.
Includes front-end JavaScript libraries with known security vulnerabilities
4 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers. Learn more.
General
Missing source maps for large first-party JavaScript
Source maps translate minified code to the original source code. This helps developers debug in production. In addition, Lighthouse is able to provide further insights. Consider deploying source maps to take advantage of these benefits. Learn more.
User Experience

Link text (and alternate text for images, when used as links) that is discernible, unique, and focusable improves the navigation experience for screen reader users. Learn more.
Form elements do not have associated labels
Labels ensure that form controls are announced properly by assistive technologies, like screen readers. Learn more.
Buttons do not have an accessible name
When a button doesn't have an accessible name, screen readers announce it as "button", making it unusable for users who rely on screen readers. Learn more.
Tables and lists
These are opportunities to improve the experience of reading tabular or list data using assistive technology, like a screen reader.
Lists do not contain only `<li>` elements and script supporting elements (`<script>` and `<template>`).
Screen readers have a specific way of announcing lists. Ensuring proper list structure aids screen reader output. Learn more.
ARIA
