Minify JavaScript. Potential savings of 6 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. 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
Third-party code blocked the main thread for 4,660 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.
Minimize main-thread work
18.9 s

Consider marking your touch and wheel event listeners as `passive` to improve your page's scroll performance. Learn more.
Avoid enormous network payloads
Total size was 8,061 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
70 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more.
Reduce JavaScript execution time
9.0 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn more.
Avoid large layout shifts
5 elements found
These DOM elements contribute most to the CLS of the page.
Avoid chaining critical requests
36 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
Keep request counts low and transfer sizes small
94 requests • 8,061 KiB
To set budgets for the quantity and size of page resources, add a budget.json file. Learn more.

Heaad.ru Mobile SEO: 86/100
Quick overview:
Content Best Practices
Format your HTML in a way that enables crawlers to better understand your app’s content.
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.
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

Heaad.ru Mobile Best Practices: 60/100
Quick overview:
Trust and Safety
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.
Does not use HTTPS
8 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.
Ensure CSP is effective against XSS attacks
A strong Content Security Policy (CSP) significantly reduces the risk of cross-site scripting (XSS) attacks. Learn more
General
Issues were logged in the `Issues` panel in Chrome Devtools
Issues logged to the `Issues` panel in Chrome Devtools indicate unresolved problems. They can come from network request failures, insufficient security controls, and other browser concerns. Open up the Issues panel in Chrome DevTools for more details on each issue.
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
User Experience
Displays images with incorrect aspect ratio
Image display dimensions should match natural aspect ratio. Learn more.
Serves images with low resolution
Image natural dimensions should be proportional to the display size and the pixel ratio to maximize image clarity. Learn more.
