Dallashistory.org Test Results
Dallashistory.org Mobile Performance: 28/100
Quick overview:
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Eliminate render-blocking resources
Potential savings of 150 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
Potential savings of 228 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.
Reduce the impact of third-party code
Third-party code blocked the main thread for 310 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 how to minimize third-party impact.
Largest Contentful Paint element
12,110 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Reduce unused JavaScript
Potential savings of 695 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.
Minimize main-thread work
4.9 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
Reduce initial server response time
Root document took 1,690 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.
Efficiently encode images
Potential savings of 212 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
Minify JavaScript
Potential savings of 355 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
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.
Serve images in next-gen formats
Potential savings of 573 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 JavaScript execution time
1.9 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn how to reduce Javascript execution time.
Properly size images
Potential savings of 66 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
Avoid large layout shifts
3 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
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.
Avoid serving legacy JavaScript to modern browsers
Potential savings of 5 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
Serve static assets with an efficient cache policy
67 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
First Meaningful Paint
8.2 s
First Meaningful Paint measures when the primary content of a page is visible. Learn more about the First Meaningful Paint metric.
Time to Interactive
12.9 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.
Max Potential First Input Delay
400 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.
Dallashistory.org Mobile SEO: 92/100
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.
Dallashistory.org Mobile Best Practices: 83/100
Quick overview:
General
Missing source maps for large first-party JavaScript
Source maps translate minified code to the original source code. This helps developers debug in production. In addition, Lighthouse is able to provide further insights. Consider deploying source maps to take advantage of these benefits. Learn more about source maps.
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.
Dallashistory.org Mobile Accessibility: 85/100
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 have `[alt]` attributes that are redundant text.
Informative elements should aim for short, descriptive alternative text. Alternative text that is exactly the same as the text adjacent to the link or image is potentially confusing for screen reader users, because the text will be read twice. 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.
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.
Contrast
These are opportunities to improve the legibility of your content.
Links rely on color to be distinguishable.
Low-contrast text is difficult or impossible for many users to read. Link text that is discernible improves the experience for users with low vision. Learn how to make links distinguishable.
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.
