Aa4be.com Test Results

Aa4be.com Mobile Performance: 62/100
Quick overview:
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Avoid multiple page redirects
Est savings of 610 ms
Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
Largest Contentful Paint element
8,560 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Reduce initial server response time
Root document took 660 ms
Keep the server response time for the main document short because all other requests depend on it. Learn more about the Time to First Byte metric.
Eliminate render-blocking resources
Est savings of 760 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.
Properly size images
Est savings of 3,472 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
Enable text compression
Est savings of 14 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more about text compression.
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
Serve static assets with an efficient cache policy
18 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
Avoid enormous network payloads
Total size was 8,574 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
Minify CSS
Est savings of 3 KiB
Minifying CSS files can reduce network payload sizes. Learn how to minify CSS.
Reduce unused JavaScript
Est savings of 23 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.
Improve image delivery
Est savings of 5,582 KiB
Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size
Network dependency tree
Avoid chaining critical requests by reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.
LCP request discovery
Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading
Use efficient cache lifetimes
Est savings of 8,624 KiB
A long cache lifetime can speed up repeat visits to your page. Learn more.
Forced reflow
Many APIs, typically reading layout geometry, force the rendering engine to pause script execution in order to calculate the style and layout. Learn more about forced reflow and its mitigations.
Render blocking requests
Requests are blocking the page's initial render, which may delay LCP. Deferring or inlining can move these network requests out of the critical path.
Document request latency
Est savings of 13 KiB
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Time to Interactive
8.6 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.

Aa4be.com Mobile SEO: 58/100
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 about the `alt` attribute.
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.
Document doesn't have a `<title>` element
The title gives screen reader users an overview of the page, and search engine users rely on it heavily to determine if a page is relevant to their search. Learn more about document titles.
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 how to make links crawlable
robots.txt is not valid
If your robots.txt file is malformed, crawlers may not be able to understand how you want your website to be crawled or indexed. Learn more about robots.txt. Lighthouse was unable to download a robots.txt file

Aa4be.com Mobile Best Practices: 76/100
Quick overview:
General
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 about this errors in console diagnostic audit
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.
Browser Compatibility
Page lacks the HTML doctype, thus triggering quirks-mode
Specifying a doctype prevents the browser from switching to quirks-mode. Learn more about the doctype declaration. Document must contain a doctype
Aa4be.com Mobile Accessibility: 42/100
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.
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.
Document doesn't have a `<title>` element
The title gives screen reader users an overview of the page, and search engine users rely on it heavily to determine if a page is relevant to their search. Learn more about document titles.
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 how to provide sufficient color contrast.
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 about the viewport meta tag.
