Minifying JavaScript files can reduce payload sizes and script parse time. [Learn how to minify JavaScript].
hreflang links tell search engines what version of a page they should list in search results for a given language or region. [Learn more about `hreflang`].
This is the largest contentful element painted within the viewport. [Learn more about the Largest Contentful Paint element]
Third party code can significantly impact load performance. [Reduce and defer loading of third party code] to prioritize your page's content.
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. [Learn how to reduce unused JavaScript].
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. [Learn more about text compression].
Form elements without effective labels can create frustrating experiences for screen reader users. [Learn more about the `select` element].
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].
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].
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]
Low-contrast text is difficult or impossible for many users to read. [Learn how to provide sufficient color contrast].
Labels ensure that form controls are announced properly by assistive technologies, like screen readers. [Learn more about form element labels].
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
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.
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].
Meta descriptions may be included in search results to concisely summarize page content. [Learn more about the meta description].
Minifying CSS files can reduce network payload sizes. [Learn how to minify CSS].
Serve images that are appropriately-sized to save cellular data and improve load time. [Learn how to size images].
Optimized images load faster and consume less cellular data. [Learn how to efficiently encode images].
Descriptive link text helps search engines understand your content. [Learn how to make links more accessible].
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]
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].
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].
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].
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]
