Lvsl.ru Mobile Performance: 23/100
These suggestions can help your page load faster. They don't directly affect the Performance score.
Preload key requests. Potential savings of 10,230 ms
Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load. Learn more.
Preload Largest Contentful Paint image. Potential savings of 4,950 ms
Preload the image used by the LCP element in order to improve your LCP time. Learn more.
Properly size images. Potential savings of 312 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn more.
Serve images in next-gen formats. Potential savings of 262 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.
Use video formats for animated content. Potential savings of 198 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
Avoid multiple page redirects. Potential savings of 1,260 ms
Redirects introduce additional delays before the page can be loaded. Learn more.
Efficiently encode images. Potential savings of 136 KiB
Optimized images load faster and consume less cellular data. Learn more.
Remove unused CSS. Potential savings of 85 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.
More information about the performance of your application. These numbers don't directly affect the Performance score.
For users on slow connections, external scripts dynamically injected via `document.write()` can delay page load by tens of seconds. Learn more.
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
Reduce the impact of third-party code
Third-party code blocked the main thread for 600 ms
Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading. Learn more.
Avoid an excessive DOM size
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn more.
Minimize main-thread work
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn more
Serve static assets with an efficient cache policy
25 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more.
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn more.
Avoids enormous network payloads
Total size was 2,423 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn more.
Keep request counts low and transfer sizes small
141 requests • 2,423 KiB
To set budgets for the quantity and size of page resources, add a budget.json file. Learn more.
Avoid non-composited animations
9 animated elements found
Animations which are not composited can be janky and increase CLS. Learn more
Avoid large layout shifts
5 elements found
These DOM elements contribute most to the CLS of the page.
Avoid chaining critical requests
4 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.
Largest Contentful Paint element
1 element found
This is the largest contentful element painted within the viewport. Learn More
Avoid long main-thread tasks
20 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay. Learn more
Lvsl.ru Mobile SEO: 86/100
Content Best Practices
Format your HTML in a way that enables crawlers to better understand your app’s content.
Crawling and Indexing
To appear in search results, crawlers need access to your app.
Links are not crawlable
Search engines may use `href` attributes on links to crawl websites. Ensure that the `href` attribute of anchor elements links to an appropriate destination, so more pages of the site can be discovered. Learn More
Lvsl.ru Mobile Best Practices: 67/100
Browser errors were logged to the console
Errors logged to the console indicate unresolved problems. They can come from network request failures and other browser concerns. 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
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.
Trust and Safety
Links to cross-origin destinations are unsafe
Add `rel="noopener"` or `rel="noreferrer"` to any external links to improve performance and prevent security vulnerabilities. Learn more.
4 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers. Learn more.
Does not use HTTPS
2 insecure requests 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.
Lvsl.ru Mobile Progressive Web App: 50/100
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. No manifest was fetched
Does not set a theme color for the address bar.
The browser address bar can be themed to match your site. Learn more. Failures: No manifest was fetched.
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: No manifest was fetched.
Does not register a service worker that controls page and `start_url`
The service worker is the technology that enables your app to use many Progressive Web App features, such as offline, add to homescreen, and push notifications. Learn more. This page is controlled by a service worker, however no `start_url` was found because no manifest was fetched.
Web app manifest or service worker do not meet the installability requirements
Service worker is the technology that enables your app to use many Progressive Web App features, such as offline, add to homescreen, and push notifications. With proper service worker and manifest implementations, browsers can proactively prompt users to add your app to their homescreen, which can lead to higher engagement. Learn more.
Lvsl.ru Mobile Accessibility: 60/100
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.
Image elements do not have `[alt]` attributes
Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute. Learn more.
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.
These items highlight common accessibility best practices.
`[user-scalable="no"]` is used in the `<meta name="viewport">` element or the `[maximum-scale]` attribute is less than 5.
Disabling zooming is problematic for users with low vision who rely on screen magnification to properly see the contents of a web page. Learn more.
These are opportunities to improve the legibility of your content.
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.
