Chrome UX Report (opens in a new tab): real Chrome visitors over rolling 28-day periods.
One score from every part of this review. How it works
Speed
Reduce unused JavaScript
2.0 s · 682 KiBAbout 682 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.0 s faster on a phone.
Main-thread work: 10.5 s
A phone's processor spends 10.5 s on main-thread work while loading, 6.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.
Mobile performance score: 38
38/100Your mobile performance score is 38. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.
8 third-party services on the page
8 third-party services load with your homepage (ZenDesk, Clarity and loox.io and others), adding 1.7 MB and 1.8 s of main-thread time.
Render-blocking requests
700 ms12 files block the first paint until they finish downloading. Deferring or inlining them could save about 700 ms.
Use efficient cache lifetimes
400 ms · 293 KiB31 files are served with short cache lifetimes, so returning visitors download them again (293 KiB).
ZenDesk adds 608 ms
608 msZenDesk costs a phone 608 ms of main-thread work and 479 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.
Reduce unused CSS
450 ms · 56 KiBAbout 56 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.
20 long tasks on the main thread
20 long tasks block the main thread while loading, the longest for 347 ms. During a long task the page ignores taps.
Clarity adds 287 ms
287 msClarity costs a phone 287 ms of main-thread work and 29 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.
loox.io adds 254 ms
254 msloox.io costs a phone 254 ms of main-thread work and 127 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.
Klaviyo adds 200 ms
200 msKlaviyo costs a phone 200 ms of main-thread work and 328 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.
Shopify adds 158 ms
158 msShopify costs a phone 158 ms of main-thread work and 455 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.
Improve image delivery
250 ms · 155 KiB8 images could be 155 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 250 ms faster on a phone.
Legacy JavaScript
51 KiBPolyfills for old browsers add 51 KiB JavaScript that modern phones do not need.
Font display
50 msWeb fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).
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.
Forced reflow
Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.
Minify JavaScript
5 KiB5 KiB could be saved by minifying JavaScript.
Duplicated JavaScript
2 KiB2 KiB JavaScript is shipped twice across bundles.

First Contentful Paint: 1.9 s
1.9 sThe first text or image appears after 1.9 s on a phone. Good is under 1.8 s.

Images and page weight
Page weight: 15.4 MB in 445 requests
15.4 MBYour homepage downloads 15.4 MB in 445 requests on a phone: media 11.4 MB (2), scripts 1.8 MB (114) and other files 1.4 MB (266). Under 2 MB keeps phones on slow connections fast.
1 image far larger than shown
2 KiB1 image is downloaded at several times the size a phone draws it, for example ba.jpg at 1,160 px wide, shown at 378 px. Resized copies would save about 2 KiB.
About 4.4 g of CO₂ per visit
4.35 gBy the Sustainable Web Design model, a visit to your homepage emits about 4.35 g of CO₂e: 522.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
