Preload Largest Contentful Paint image
Est savings of 280 ms
If the LCP element is dynamically added to the page, you should preload the image in order to improve LCP. Learn more about preloading LCP elements.
Eliminate render-blocking resources
Est savings of 1,390 ms
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.
Minify JavaScript
Est savings of 13 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.

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.
Serve static assets with an efficient cache policy
37 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
Properly size images
Est savings of 240 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
Forced reflow
Many APIs, typically reading layout geometry, force the rendering engine to pause script execution in order to calculate the style and layout. Learn more about forced reflow and its mitigations.
LCP request discovery
Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading
Optimize DOM size
A large DOM can increase the duration of style calculations and layout reflows, impacting page responsiveness. A large DOM will also increase memory usage. Learn how to avoid an excessive DOM size.
Use efficient cache lifetimes
Est savings of 177 KiB
A long cache lifetime can speed up repeat visits to your page. Learn more.
Render blocking requests
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.
Document request latency
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Improve image delivery
Est savings of 1,130 KiB
Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size
Time to Interactive
4.4 s

Learn more about HTTPS.
Does not redirect HTTP traffic to HTTPS
Make sure that you redirect all HTTP traffic to HTTPS in order to enable secure web features for all your users. Learn more.
User Experience
Serves images with low resolution
Image natural dimensions should be proportional to the display size and the pixel ratio to maximize image clarity. Learn how to provide responsive images.
