Low-contrast text is difficult or impossible for many users to read. [Learn how to provide sufficient color contrast].
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.
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].
Reducing the download time of images can improve the perceived load time of the page and LCP. [Learn more about optimizing image size]
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. [Learn how to reduce unused JavaScript].
A value greater than 0 implies an explicit navigation ordering. Although technically valid, this often creates frustrating experiences for users who rely on assistive technologies. [Learn more about the `tabindex` attribute].
Optimized images load faster and consume less cellular data. [Learn how to efficiently encode images].
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].
Third party code can significantly impact load performance. [Reduce and defer loading of third party code] to prioritize your page's content.
Minifying CSS files can reduce network payload sizes. [Learn how to minify CSS].
Redirects introduce additional delays before the page can be loaded. [Learn how to avoid page redirects].
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].
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]
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].
Screen readers have a specific way of announcing lists. Ensuring proper list structure aids screen reader output. [Learn more about proper list structure].
Screen readers require list items (`
Deprecated APIs will eventually be removed from the browser. [Learn more about deprecated APIs].
Form elements without effective labels can create frustrating experiences for screen reader users. [Learn more about the `select` element].
Descriptive link text helps search engines understand your content. [Learn how to make links more accessible].
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]
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
This is the largest contentful element painted within the viewport. [Learn more about the Largest Contentful Paint element]
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].
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].
Optimize LCP by making the LCP image [discoverable] from the HTML immediately, and [avoiding lazy-loading]
Serve images that are appropriately-sized to save cellular data and improve load time. [Learn how to size images].
