Opportunities (7)

  1. Use video formats for animated content

    Estimated savings 123.93 s

    Large GIFs are inefficient for delivering animated content. Consider using MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF to save network bytes. Learn more about efficient video formats

  1. Eliminate render-blocking resources

    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.

  2. Avoid multiple page redirects

    Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.

  3. Enable text compression

    Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more about text compression.

  4. Preconnect to required origins

    Consider adding preconnect or dns-prefetch resource hints to establish early connections to important third-party origins. Learn how to preconnect to required origins.

  5. Preload key requests

    Consider using <link rel=preload> to prioritize fetching resources that are currently requested later in page load. Learn how to preload key requests.

  6. All text remains visible during webfont loads

    Leverage the font-display CSS feature to ensure text is user-visible while webfonts are loading. Learn more about font-display.

  7. Minify JavaScript

  10. Preload Largest Contentful Paint image

    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.

  11. Largest Contentful Paint image was not lazily loaded

    Above-the-fold images that are lazily loaded render later in the page lifecycle, which can delay the largest contentful paint. Learn more about optimal lazy loading.

    Element
    header.flex > div.header__logo > a > img.inline-block

  12. Minimize third-party usage

    Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading. Learn how to minimize third-party impact.

  13. Lazy load third-party resources with facades

    Some third-party embeds can be lazy loaded. Consider replacing them with a facade until they are required. Learn how to defer third-parties with a facade.

  14. Remove duplicate modules in JavaScript bundles

    Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.

  15. Has a <meta name="viewport"> tag with width or initial-scale

    A <meta name="viewport"> 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.

  16. Avoid non-composited animations

    Animations which are not composited can be janky and increase CLS. Learn how to avoid non-composited animations

  17. Defer offscreen images
