⚠️
Reduce unused CSS
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](https://developer.chrome.com/docs/lighthouse/performance/unused-css-rules/).
0/100
⚠️
Use efficient cache lifetimes
A long cache lifetime can speed up repeat visits to your page. [Learn more about caching](https://developer.chrome.com/docs/performance/insights/cache).
0/100
⚠️
LCP breakdown
Each [subpart has specific improvement strategies](https://developer.chrome.com/docs/performance/insights/lcp-breakdown). Ideally, most of the LCP time should be spent on loading the resources, not within delays.
0/100
⚠️
Network dependency tree
[Avoid chaining critical requests](https://developer.chrome.com/docs/performance/insights/network-dependency-tree) by reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.
0/100
⚠️
Render-blocking requests
Requests are blocking the page's initial render, which may delay LCP. [Deferring or inlining](https://developer.chrome.com/docs/performance/insights/render-blocking) can move these network requests out of the critical path.
0/100
⚠️
Speed Index
Speed Index shows how quickly the contents of a page are visibly populated. [Learn more about the Speed Index metric](https://developer.chrome.com/docs/lighthouse/performance/speed-index/).
2/100
⚠️
Font display
Consider setting [font-display](https://developer.chrome.com/docs/performance/insights/font-display) to swap or optional to ensure text is consistently visible. swap can be further optimized to mitigate layout shifts with [font metric overrides](https://developer.chrome.com/blog/font-fallbacks).
50/100
⚠️
Image elements do not have explicit `width` and `height`
Set an explicit width and height on image elements to reduce layout shifts and improve CLS. [Learn how to set image dimensions](https://web.dev/articles/optimize-cls#images_without_dimensions)
50/100
⚠️
First Contentful Paint
First Contentful Paint marks the time at which the first text or image is painted. [Learn more about the First Contentful Paint metric](https://developer.chrome.com/docs/lighthouse/performance/first-contentful-paint/).
54/100
⚠️
Largest Contentful Paint
Largest Contentful Paint marks the time at which the largest text or image is painted. [Learn more about the Largest Contentful Paint metric](https://developer.chrome.com/docs/lighthouse/performance/lighthouse-largest-contentful-paint/)
