If the LCP element is dynamically added to the page, you should preload the image in order to improve LCP. Learn more about preloading LCP elements.
Avoid `document.write()`
For users on slow connections, external scripts dynamically injected via `document.write()` can delay page load by tens of seconds. Learn how to avoid document.write().
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
114 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
Avoid serving legacy JavaScript to modern browsers
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
Time to Interactive
51.7 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
280 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.
Bbsdump.com Mobile SEO: 83/100
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
Bbsdump.com Mobile Best Practices: 52/100
Quick overview:
User Experience
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.
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.
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.
General
Uses deprecated APIs
1 warning found
Deprecated APIs will eventually be removed from the browser. Learn more about deprecated APIs.
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.
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 contains a `doctype` that triggers `limited-quirks-mode`
Bbsdump.com Mobile Accessibility: 62/100
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.
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.
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.
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.
Internationalization and localization
These are opportunities to improve the interpretation of your content by users in different locales.
`<html>` element does not have a `[lang]` attribute
If a page doesn't specify a `lang` attribute, a screen reader assumes that the page is in the default language that the user chose when setting up the screen reader. If the page isn't actually in the default language, then the screen reader might not announce the page's text correctly. Learn more about the `lang` attribute.
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.
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.
