Insights

Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.

Polyfills and transforms enable older 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 older browsers. Learn why most sites can deploy ES6+ code without transpiling

3rd party code can significantly impact load performance. Reduce and defer loading of 3rd party code to prioritize your page's content.

A long cache lifetime can speed up repeat visits to your page. Learn more about caching.

Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.

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.

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.

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.

description: [preconnect](https://developer.chrome.com/docs/lighthouse/performance/uses-rel-preconnect/) hints help the browser establish a connection earlier in the page load, saving time when the first request for that origin is made. The following are the origins that the page preconnected to.

title: Preconnected origins

value: no origins were preconnected

description: Add [preconnect](https://developer.chrome.com/docs/lighthouse/performance/uses-rel-preconnect/) hints to your most important origins, but try to use no more than 4.

title: Preconnect candidates

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.

Accessibility

These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.

ARIA

Some ARIA parent roles must contain specific child roles to perform their intended accessibility functions. Learn more about roles and required children elements.

Failing Elements
Explore the Masters experience Let's create smarter business `div.cds--col-lg-6 > div > div#mbox-leadspace_cta > c4d-button-group.leadspace-expanded__action`

Some ARIA child roles must be contained by specific parent roles to properly perform their intended accessibility functions. Learn more about ARIA roles and required parent element.

Failing Elements

Let's create smarter business `div#mbox-leadspace_cta > c4d-button-group.leadspace-expanded__action > a > c4d-button-group-item`

When an element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers. Learn how to make command elements more accessible.

Failing Elements
c4d-masthead-container > c4d-masthead > c4d-masthead-global-bar > div.earth-language-icon `c4d-masthead-container > c4d-masthead > c4d-masthead-global-bar > div.earth-language-icon`

These are opportunities to improve the usage of ARIA in your application which may enhance the experience for users of assistive technology, like a screen reader.

Names and labels

When a button doesn't have an accessible name, screen readers announce it as "button", making it unusable for users who rely on screen readers. Learn how to make buttons more accessible.

Failing Elements
Pause `div.c4d--video-player__video-container > button.c4d--video-player__toggle-playback`

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.

Navigation

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.

Failing Elements
Recommended for you `div#table-of-contents-b422012d4b > div#mbox-tg1-tg > div.cds--col > h5.expressive-heading-02`
Professional training `c4d-cta-block.title-plus-3-items-layout > c4d-cta-block-item-row > c4d-cta-block-item > c4d-content-item-heading`

These are opportunities to improve keyboard navigation in your application.

Tables and lists

Screen readers have a specific way of announcing lists. Ensuring proper list structure aids screen reader output. Learn more about proper list structure.

Failing Elements
nav.c4d--legal-nav > div.c4d--legal-nav__list > ul `nav.c4d--legal-nav > div.c4d--legal-nav__list > ul`

These are opportunities to improve the experience of reading tabular or list data using assistive technology, like a screen reader.

Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.

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.

Accessibility

ARIA

Some ARIA parent roles must contain specific child roles to perform their intended accessibility functions. Learn more about roles and required children elements.

Failing Elements
Explore the Masters experience Let's create smarter business `div.cds--col-lg-6 > div > div#mbox-leadspace_cta > c4d-button-group.leadspace-expanded__action`

Some ARIA child roles must be contained by specific parent roles to properly perform their intended accessibility functions. Learn more about ARIA roles and required parent element.

Failing Elements

Let's create smarter business `div#mbox-leadspace_cta > c4d-button-group.leadspace-expanded__action > a > c4d-button-group-item`

These are opportunities to improve the usage of ARIA in your application which may enhance the experience for users of assistive technology, like a screen reader.

Names and labels

When a button doesn't have an accessible name, screen readers announce it as "button", making it unusable for users who rely on screen readers. Learn how to make buttons more accessible.

Failing Elements
Pause `div.c4d--video-player__video-container > button.c4d--video-player__toggle-playback`

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.

Failing Elements
div#container-35bfd5ef7a > div.short-banner > c4d-promo-banner.short-banner__promo-banner > a `div#container-35bfd5ef7a > div.short-banner > c4d-promo-banner.short-banner__promo-banner > a`

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.

Navigation

Failing Elements
Latest News `div#mbox-leadspace-side > div.leadspace-newsfeed > c4d-link-list.newsfeed > c4d-link-list-heading`
Professional training `c4d-cta-block.title-plus-3-items-layout > c4d-cta-block-item-row > c4d-cta-block-item > c4d-content-item-heading`

These are opportunities to improve keyboard navigation in your application.

Tables and lists

Screen readers have a specific way of announcing lists. Ensuring proper list structure aids screen reader output. Learn more about proper list structure.

Failing Elements
nav.c4d--legal-nav > div.c4d--legal-nav__list > ul `nav.c4d--legal-nav > div.c4d--legal-nav__list > ul`

These are opportunities to improve the experience of reading tabular or list data using assistive technology, like a screen reader.
