These suggestions can help your page load faster. They don't directly affect the Performance score.
Remove unused JavaScript. Potential savings of 511 KiB
Remove unused JavaScript to reduce bytes consumed by network activity. Learn more.
Serve images in next-gen formats. Potential savings of 291 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.
Eliminate render-blocking resources. Potential savings of 1,480 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 174 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.
Reduce initial server response time. Root document took 1,490 ms
Keep the server response time for the main document short because all other requests depend on it. Learn more.
Defer offscreen images. Potential savings of 145 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. Learn more.
Efficiently encode images. Potential savings of 104 KiB
Optimized images load faster and consume less cellular data. Learn more.
Properly size images. Potential savings of 43 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn more.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Does not use passive listeners to improve scrolling performance
Consider marking your touch and wheel event listeners as `passive` to improve your page's scroll performance. Learn more.
Minimize main-thread work
11.1 s
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
51 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more.
Avoid an excessive DOM size
2,123 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn more.
Reduce JavaScript execution time
5.7 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. 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
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.
Avoid large layout shifts
4 elements found
These DOM elements contribute most to the CLS of the page.
Keep request counts low and transfer sizes small
80 requests • 1,978 KiB
To set budgets for the quantity and size of page resources, add a budget.json file. Learn more.
Largest Contentful Paint element
1 element found
This is the largest contentful element painted within the viewport. Learn More

Rutube.ru Mobile Best Practices: 69/100
Quick overview:
General
Browser errors were logged to the console

Trust and Safety
Includes front-end JavaScript libraries with known security vulnerabilities
1 vulnerability detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers. 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.
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.

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.

Quick overview:
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.

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.
`<frame>` or `<iframe>` elements do not have a title
Screen reader users rely on frame titles to describe the contents of frames. 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.
Best practices
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.
