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].
Largest Contentful Paint marks the time at which the largest text or image is painted. [Learn more about the Largest Contentful Paint metric]
Optimized images load faster and consume less cellular data. [Learn how to efficiently encode images].
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 large DOM will increase memory usage, cause longer [style calculations], and produce costly [layout reflows]. [Learn how to avoid an excessive DOM size].
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. [Learn how to minimize main-thread work]
Search engines may use `href` attributes on links to crawl websites. Ensure that the `href` attribute of anchor elements links to an appropriate destination, so more pages of the site can be discovered. [Learn how to make links crawlable]
Third party code can significantly impact load performance. [Reduce and defer loading of third party code] to prioritize your page's content.
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. [Learn more about source maps].
Disabling zooming is problematic for users with low vision who rely on screen magnification to properly see the contents of a web page. [Learn more about the viewport meta tag].
Serve images that are appropriately-sized to save cellular data and improve load time. [Learn how to size images].
This is the largest contentful element painted within the viewport. [Learn more about the Largest Contentful Paint element]
Keep the server response time for the main document short because all other requests depend on it. [Learn more about the Time to First Byte metric].
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.
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].
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].
Redirects introduce additional delays before the page can be loaded. [Learn how to avoid page redirects].
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].
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. [Learn how to reduce Javascript execution time].
Deprecated APIs will eventually be removed from the browser. [Learn more about deprecated APIs].
