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].
Speed Index shows how quickly the contents of a page are visibly populated. [Learn more about the Speed Index metric].
Image display dimensions should match natural aspect ratio. [Learn more about image aspect ratio].
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].
Make sure that you redirect all HTTP traffic to HTTPS in order to enable secure web features for all your users. [Learn more].
Serve images that are appropriately-sized to save cellular data and improve load time. [Learn how to size images].
Meta descriptions may be included in search results to concisely summarize page content. [Learn more about the meta description].
Redirects introduce additional delays before the page can be loaded. [Learn how to avoid page redirects].
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].
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].
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.
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.
Reducing the download time of images can improve the perceived load time of the page and LCP. [Learn more about optimizing image size]
Third party code can significantly impact load performance. [Reduce and defer loading of third party code] to prioritize your page's content.
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].
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]
Optimize LCP by making the LCP image [discoverable] from the HTML immediately, and [avoiding lazy-loading]
