First Contentful Paint marks the time at which the first text or image is painted. [Learn more about the First Contentful Paint metric].
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].
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.
Optimize LCP by making the LCP image [discoverable] from the HTML immediately, and [avoiding lazy-loading]
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Make sure that you redirect all HTTP traffic to HTTPS in order to enable secure web features for all your users. [Learn more].
Third party code can significantly impact load performance. [Reduce and defer loading of third party code] to prioritize your page's content.
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. [Learn more about text compression].
Speed Index shows how quickly the contents of a page are visibly populated. [Learn more about the Speed Index metric].
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]
Largest Contentful Paint marks the time at which the largest text or image is painted. [Learn more about the Largest Contentful Paint metric]
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].
Minifying JavaScript files can reduce payload sizes and script parse time. [Learn how to minify JavaScript].
This is the largest contentful element painted within the viewport. [Learn more about the Largest Contentful Paint element]
Minifying CSS files can reduce network payload sizes. [Learn how to minify CSS].
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. [Learn how to reduce unused JavaScript].
Descriptive link text helps search engines understand your content. [Learn how to make links more accessible].
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].
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].
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].
Deprecated APIs will eventually be removed from the browser. [Learn more about deprecated APIs].
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. [Learn how to defer offscreen images].
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].
Optimized images load faster and consume less cellular data. [Learn how to efficiently encode images].
