Speed

6 to fix80

  • Render-blocking requests

    1.0 s

    1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 1.0 s.

  • Mobile performance score: 80

    80/100

    Your mobile performance score is 80. Pages that score under 90 lose visitors before the first paint.

  • Improve image delivery

    450 ms · 22 KiB

    1 image could be 22 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 450 ms faster on a phone.

  • Reduce unused JavaScript

    300 ms · 64 KiB

    About 64 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

  • Reduce unused CSS

    300 ms · 57 KiB

    About 57 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

  • website-files.com adds 213 ms

    213 ms

    website-files.com costs a phone 213 ms of main-thread work and 497 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

  • 3 third-party services on the page

    3 third-party services load with your homepage (website-files.com, cloudfront.net and Fastly), adding 775 KiB and 240 ms of main-thread time.

  • 2 long tasks on the main thread

    2 long tasks block the main thread while loading, the longest for 63 ms. During a long task the page ignores taps.

  • Chained critical requests

    Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

2 checks passed

  • Main-thread work: 0.9 s

    A phone's processor spends 0.9 s on main-thread work while loading, 303 ms of it running JavaScript. That is comfortably low.

  • Server response: 132 ms

    132 ms

    Your server sent the HTML in 132 ms, well inside Google's 600 ms guideline.
