Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.

Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.

This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element

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

Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. Learn how to reduce unused JavaScript.

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.

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

Set an explicit width and height on image elements to reduce layout shifts and improve CLS. Learn how to set image dimensions

Many APIs, typically reading layout geometry, force the rendering engine to pause script execution in order to calculate the style and layout. Learn more about forced reflow and its mitigations.

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

Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size

A large DOM can increase the duration of style calculations and layout reflows, impacting page responsiveness. A large DOM will also increase memory usage. Learn how to avoid an excessive DOM size.

Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading

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.

Layout shifts occur when elements move absent any user interaction. Investigate the causes of layout shifts, such as elements being added, removed, or their fonts changing as the page loads.

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

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.

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.

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.

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

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.

Screen reader users rely on frame titles to describe the contents of frames. Learn more about frame titles.

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.

Low-contrast text is difficult or impossible for many users to read. Learn how to provide sufficient color contrast.

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