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].
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]
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].
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. [Learn more about text compression].
Low-contrast text is difficult or impossible for many users to read. [Learn how to provide sufficient color contrast].
Meta descriptions may be included in search results to concisely summarize page content. [Learn more about the meta description].
Speed Index shows how quickly the contents of a page are visibly populated. [Learn more about the Speed Index metric].
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].
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].
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. [Learn how to reduce unused JavaScript].
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].
Minifying JavaScript files can reduce payload sizes and script parse time. [Learn how to minify JavaScript].
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Third party code can significantly impact load performance. [Reduce and defer loading of third party code] to prioritize your page's content.
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.
A large DOM will increase memory usage, cause longer [style calculations], and produce costly [layout reflows]. [Learn how to avoid an excessive DOM size].
Minifying CSS files can reduce network payload sizes. [Learn how to minify CSS].
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]
