Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. [Learn more about text compression].
Meta descriptions may be included in search results to concisely summarize page content. [Learn more about the meta description].
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.
Minifying JavaScript files can reduce payload sizes and script parse time. [Learn how to minify JavaScript].
Minifying CSS files can reduce network payload sizes. [Learn how to minify CSS].
Descriptive link text helps search engines understand your content. [Learn how to make links more accessible].
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].
Labels ensure that form controls are announced properly by assistive technologies, like screen readers. [Learn more about form element labels].
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].
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].
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].
This is the largest contentful element painted within the viewport. [Learn more about the Largest Contentful Paint element]
Issues logged to the `Issues` panel in Chrome Devtools indicate unresolved problems. They can come from network request failures, insufficient security controls, and other browser concerns. Open up the Issues panel in Chrome DevTools for more details on each issue.
Low-contrast text is difficult or impossible for many users to read. [Learn how to provide sufficient color contrast].
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]
If your robots.txt file is malformed, crawlers may not be able to understand how you want your website to be crawled or indexed. [Learn more about robots.txt].
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
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].
Third party code can significantly impact load performance. [Reduce and defer loading of third party code] to prioritize your page's content.
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].
Screen reader users rely on frame titles to describe the contents of frames. [Learn more about frame titles].
First Contentful Paint marks the time at which the first text or image is painted. [Learn more about the First Contentful Paint metric].
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]
