Nisbar.me Test Results
Nisbar.me Mobile Performance: 69/100
Quick overview:
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.
Document request latency
Est savings of 2,060 ms
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Improve image delivery
Est savings of 4,028 KiB
Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size
Use efficient cache lifetimes
Est savings of 680 KiB
A long cache lifetime can speed up repeat visits to your page. Learn more.
LCP request discovery
Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading
Render blocking requests
Est savings of 1,530 ms
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.
Font display
Est savings of 100 ms
Consider setting font-display to swap or optional to ensure text is consistently visible. swap can be further optimized to mitigate layout shifts with font metric overrides.
Forced reflow
A forced reflow occurs when JavaScript queries geometric properties (such as offsetWidth) after styles have been invalidated by a change to the DOM state. This can result in poor performance. Learn more about forced reflows and possible mitigations.
Time to Interactive
6.9 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.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Eliminate render-blocking resources
Est savings of 1,630 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 CSS
Est savings of 39 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity. Learn how to reduce unused CSS.
Avoid multiple page redirects
Est savings of 630 ms
Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
Reduce initial server response time
Root document took 2,040 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.
Serve images in next-gen formats
Est savings of 95 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.
Reduce unused JavaScript
Est savings of 67 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.
Largest Contentful Paint element
6,870 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Serve static assets with an efficient cache policy
170 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
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`.
Defer offscreen images
Est savings of 4 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 enormous network payloads
Total size was 7,028 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
Properly size images
Est savings of 74 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
Avoid an excessive DOM size
2,170 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn how to avoid an excessive DOM size.
Avoid serving legacy JavaScript to modern browsers
Est savings of 0 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. Consider modifying your JavaScript build process to not transpile Baseline features, unless you know you must support legacy browsers. Learn why most sites can deploy ES6+ code without transpiling
Nisbar.me 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.
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.
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
Nisbar.me 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.
User Experience
Displays images with incorrect aspect ratio
Image display dimensions should match natural aspect ratio. Learn more about image aspect ratio.
Nisbar.me Mobile Accessibility: 78/100
Quick overview:
`<td>` elements in a large `<table>` do not have table headers.
Screen readers have features to make navigating tables easier. Ensuring that `<td>` elements in a large table (3 or more cells in width and height) have an associated table header may improve the experience for screen reader users. Learn more about table headers.
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.
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.
`<frame>` or `<iframe>` elements do not have a title
Screen reader users rely on frame titles to describe the contents of frames. Learn more about frame 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.
Touch targets do not have sufficient size or spacing.
Touch targets with sufficient size and spacing help users who may have difficulty targeting small controls to activate the targets. Learn more about touch targets.
