Some ARIA parent roles cannot perform their intended functions if specific child roles are not used. ARIA toggle fields have accessible names When a toggle field doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers. Buttons have an accessible name Buttons become unusable as they are announced simply as "button" when the button does not have an accessible name, when used by screen readers and other assistive technologies.
No form fields have multiple labels Form fields with multiple labels can be confusingly announced by assistive technologies like screen readers which use either the first, the last, or all of the labels.

Properly defines charset A character encoding declaration is required. Avoids Application Cache Application cache is deprecated and is no longer recommended. Name Version jQuery. has valid source maps 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. They can come from network request failures, insufficient security controls, and other browser concerns. Open up the Issues panel in Chrome DevTools for more details on each issue. Browser errors were logged to the console Below is a list of all errors logged to the console, which indicate unresolved problems on the site.
Links have descriptive text Make use of descriptive link text to assist search engines in understanding the content. Document avoids plugins The content of plugins cannot be indexed by search engines and many devices either restrict or do not support snapsext trade.

Providing servers geographically closer to the user could improve performance. Server Backend Latencies — 0 ms High server latencies indicate the server is overloaded or has a poor backend performance.

Defer offscreen images — Potential savings of 7 KiB Time to Interactive can be slowed down by resources on the. Efficiently encode images — Potential savings of 15 KiB Unoptimized images can consume more cellular data than what is necessary.
Enable text compression Text-based resources should be served with compression, such as gzip, deflate or brotli.
Preconnect to required origins Resource hints, such as 'preconnect' or 'dns-prefetch', may assist in establishing early connections to important third-party origins. Initial server response time was short — Root document snapsext trade ms Keep the server response time for the main document short because all other requests depend on it. Avoid multiple redirects — Potential savings of ms Redirects can cause additional delays before the can begin loading. Use video formats for animated content Large GIFs are inefficient for delivering animated content. However, many aren't necessary for modern browsers.
Avoids enormous network paylo — Total size was KiB Large network paylo can cost users money and are linked to long load times. Avoid chaining critical requests — 5 chains found Below is a list of Critical Request Chains, which shows which resources are loaded with a high priority. Delivering smaller JS paylo may help with this. Minimizes main-thread work — 1.
All text remains visible during webfont lo Make use of the font-display CSS feature, which will ensure text is user-visible while webfonts are loading. Minimize third-party usage snapsext trade Third-party code blocked the main thread for 40 ms It is advised to either limit, remove or delay the loading of redundant third-party code which may be ificantly impacting load performance. Lazy load third-party resources with facades Some third-party embeds can be lazy loaded. Consider replacing them with a facade until they are required.
