Quick overview:
Opportunities
These suggestions can help your page load faster. They don't directly affect the Performance score.
Properly size images. Potential savings of 464 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn more.
Remove unused JavaScript. Potential savings of 292 KiB
Remove unused JavaScript to reduce bytes consumed by network activity. Learn more.
Preload Largest Contentful Paint image. Potential savings of 2,130 ms
Preload the image used by the LCP element in order to improve your LCP time. Learn more.
Eliminate render-blocking resources. Potential savings of 880 ms

Reduce initial server response time. Root document took 730 ms
Keep the server response time for the main document short because all other requests depend on it. Learn more.
Serve images in next-gen formats. Potential savings of 71 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.
Remove unused CSS. Potential savings of 24 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.
Image elements do not have explicit `width` and `height`
Set an explicit width and height on image elements to reduce layout shifts and improve CLS. Learn more
Serve static assets with an efficient cache policy
95 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more.
Minimize main-thread work
5.3 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
3.5 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn more.
Avoid enormous network payloads
Total size was 3,992 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn more.
Avoid an excessive DOM size
878 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn more.
Avoid chaining critical requests
1 chain 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.
User Timing marks and measures
1 user timing
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences. Learn more.
Keep request counts low and transfer sizes small
122 requests • 3,992 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

Coolmic.me Mobile SEO: 98/100
Quick overview:
Mobile Friendly
Make sure your pages are mobile friendly so users don’t have to pinch or zoom in order to read the content pages. Learn more.
Tap targets are not sized appropriately
84% appropriately sized tap targets
Interactive elements like buttons and links should be large enough (48x48px), and have enough space around them, to be easy enough to tap without overlapping onto other elements. Learn more.

Coolmic.me Mobile Best Practices: 87/100
Quick overview:
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.
Registers an `unload` listener
The `unload` event does not fire reliably and listening for it can prevent browser optimizations like the Back-Forward Cache. Consider using the `pagehide` or `visibilitychange` events instead. Learn More
Trust and Safety
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 served over 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.
Coolmic.me Mobile Progressive Web App: 83/100
Quick overview:
PWA Optimized
Manifest doesn't have a maskable icon
A maskable icon ensures that the image fills the entire shape without being letterboxed when installing the app on a device. Learn more.
Is not configured for a custom splash screen
A themed splash screen ensures a high-quality experience when users launch your app from their homescreens. Learn more. Failures: Manifest does not have a PNG icon of at least 512px.
Coolmic.me Mobile Accessibility: 88/100
Quick overview:
Navigation
These are opportunities to improve keyboard navigation in your application.
Heading elements are not in a sequentially-descending order
Properly ordered headings that do not skip levels convey the semantic structure of the page, making it easier to navigate and understand when using assistive technologies. Learn more.
Names and labels
These are opportunities to improve the semantics of the controls in your application. This may enhance the experience for users of assistive technology, like a screen reader.
Links do not have a discernible name
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.
Internationalization and localization
These are opportunities to improve the interpretation of your content by users in different locales.
`<html>` element does not have a `[lang]` attribute
If a page doesn't specify a lang attribute, a screen reader assumes that the page is in the default language that the user chose when setting up the screen reader. If the page isn't actually in the default language, then the screen reader might not announce the page's text correctly. Learn more.
Contrast
These are opportunities to improve the legibility of your content.
Background and foreground colors do not have a sufficient contrast ratio.
Low-contrast text is difficult or impossible for many users to read. Learn more.
