Fcrisk.ru Test Results
Fcrisk.ru Mobile Performance: 34/100
Quick overview:
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Efficiently encode images
Potential savings of 813 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
Defer offscreen images
Potential savings of 1,103 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. Learn how to defer offscreen images.
Avoid multiple page redirects
Potential savings of 630 ms
Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
Minimize main-thread work
2.5 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn how to minimize main-thread work
Minify JavaScript
Potential savings of 69 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
Avoid serving legacy JavaScript to modern browsers
Potential savings of 25 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers. Learn how to use modern JavaScript
Avoid large layout shifts
5 layout shifts found
These are the largest layout shifts observed on the page. Each table item represents a single layout shift, and shows the element that shifted the most. Below each item are possible root causes that led to the layout shift. Some of these layout shifts may not be included in the CLS metric value due to windowing. Learn how to improve CLS
Eliminate render-blocking resources
Potential savings of 2,920 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. Learn how to eliminate render-blocking resources.
Reduce unused JavaScript
Potential savings of 99 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. Learn how to reduce unused JavaScript.
Does not have a `<meta name="viewport">` tag with `width` or `initial-scale`
A `<meta name="viewport">` not only optimizes your app for mobile screen sizes, but also prevents a 300 millisecond delay to user input. Learn more about using the viewport meta tag. No `<meta name="viewport">` tag found
Largest Contentful Paint element
11,290 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Serve images in next-gen formats
Potential savings of 1,523 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption. Learn more about modern image formats.
Enable text compression
Potential savings of 271 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more about text compression.
Minify CSS
Potential savings of 12 KiB
Minifying CSS files can reduce network payload sizes. Learn how to minify CSS.
Serve static assets with an efficient cache policy
69 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
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 how to set image dimensions
Ensure text remains visible during webfont load
Leverage the `font-display` CSS feature to ensure text is user-visible while webfonts are loading. Learn more about `font-display`.
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 about adopting passive event listeners.
Max Potential First Input Delay
540 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task. Learn more about the Maximum Potential First Input Delay metric.
Time to Interactive
14.6 s
Time to Interactive is the amount of time it takes for the page to become fully interactive. Learn more about the Time to Interactive metric.
Fcrisk.ru Mobile SEO: 85/100
Quick overview:
Content Best Practices
Format your HTML in a way that enables crawlers to better understand your app’s content.
Document does not have a meta description
Meta descriptions may be included in search results to concisely summarize page content. Learn more about the meta description.
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 about the `alt` attribute.
Fcrisk.ru Mobile Best Practices: 72/100
Quick overview:
User Experience
Document doesn't use legible font sizes
Font sizes less than 12px are too small to be legible and require mobile visitors to “pinch to zoom” in order to read. Strive to have >60% of page text ≥12px. Learn more about legible font sizes. Text is illegible because there's no viewport meta tag optimized for mobile screens.
Does not have a `<meta name="viewport">` tag with `width` or `initial-scale`
A `<meta name="viewport">` not only optimizes your app for mobile screen sizes, but also prevents a 300 millisecond delay to user input. Learn more about using the viewport meta tag. No `<meta name="viewport">` tag found
Serves images with low resolution
Image natural dimensions should be proportional to the display size and the pixel ratio to maximize image clarity. Learn how to provide responsive images.
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 about HTTPS.
Fcrisk.ru Mobile Accessibility: 74/100
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 about heading order.
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 about the `alt` attribute.
`<input type="image">` elements do not have `[alt]` text
When an image is being used as an `<input>` button, providing alternative text can help screen reader users understand the purpose of the button. Learn about input image alt text.
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 how to make links accessible.
