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]
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].
Touch targets with sufficient size and spacing help users who may have difficulty targeting small controls to activate the targets. [Learn more about touch targets].
Specifying a doctype prevents the browser from switching to quirks-mode. [Learn more about the doctype declaration].
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].
Meta descriptions may be included in search results to concisely summarize page content. [Learn more about the meta description].
Optimize LCP by making the LCP image [discoverable] from the HTML immediately, and [avoiding lazy-loading]
Speed Index shows how quickly the contents of a page are visibly populated. [Learn more about the Speed Index metric].
Low-contrast text is difficult or impossible for many users to read. [Learn how to provide sufficient color contrast].
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].
Screen readers have features to make navigating tables easier. Ensuring that `
These are the largest layout shifts observed on the page. Each table item represents a single layout shift, and shows the element that shifted the most. Below each item are possible root causes that led to the layout shift. Some of these layout shifts may not be included in the CLS metric value due to [windowing]. [Learn how to improve CLS]
Image display dimensions should match natural aspect ratio. [Learn more about image aspect ratio].
Optimized images load faster and consume less cellular data. [Learn how to efficiently encode images].
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. [Learn how to defer offscreen images].
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.
A `` not only optimizes your app for mobile screen sizes, but also prevents [a 300 millisecond delay to user input]. [Learn more about using the viewport meta tag].
