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
Render-blocking requests
1.4 s24 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.
Mobile performance score: 41
41/100Your mobile performance score is 41. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.
Main-thread work: 9.1 s
A phone's processor spends 9.1 s on main-thread work while loading, 2.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.
3,084 HTML elements
The page has 3,084 HTML elements. Above 1,500, rendering and every interaction get slower on phones.
Improve image delivery
7.9 MB61 images could be 7.9 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.
8 third-party services on the page
8 third-party services load with your homepage (Google Tag Manager, Shopify and Klaviyo and others), adding 2.4 MB and 1.6 s of main-thread time.
Reduce unused JavaScript
842 KiBAbout 842 KiB of JavaScript is downloaded but never used on this page.
Google Tag Manager adds 469 ms
469 msGoogle Tag Manager costs a phone 469 ms of main-thread work and 536 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.
Use efficient cache lifetimes
100 ms · 346 KiB31 files are served with short cache lifetimes, so returning visitors download them again (346 KiB).
20 long tasks on the main thread
20 long tasks block the main thread while loading, the longest for 402 ms. During a long task the page ignores taps.
Shopify adds 307 ms
307 msShopify costs a phone 307 ms of main-thread work and 587 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 298 ms
298 msKlaviyo costs a phone 298 ms of main-thread work and 628 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
190 KiBAbout 190 KiB of CSS is downloaded but never applied on this page.
Legacy JavaScript
76 KiBPolyfills for old browsers add 76 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).
Minify JavaScript
9 KiB9 KiB could be saved by minifying JavaScript.
Minify CSS
6 KiB6 KiB could be saved by minifying CSS.
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.

Images and page weight
Page weight: 19.7 MB in 509 requests
19.7 MBYour homepage downloads 19.7 MB in 509 requests on a phone: images 9.7 MB (100), media 5.6 MB (15) and scripts 2.7 MB (170). Under 2 MB keeps phones on slow connections fast.
37 images far larger than shown
6.0 MB37 images are downloaded at several times the size a phone draws them, for example sepiia-polo-manga-larga-hombre-gris-oscuro-warm-plus-4_3e236 at 1,200 px wide, shown at 180 px. Resized copies would save about 6.0 MB.
3 images over 500 KB
3 images weigh 1.6 MB together. On a phone connection a single image that size takes seconds.
28 images below the first screen load straight away
28 images further down the page (5.5 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.
6 images in older formats
6 images (2.7 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.
About 5.6 g of CO₂ per visit
5.59 gBy the Sustainable Web Design model, a visit to your homepage emits about 5.59 g of CO₂e: 671.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

All page content should be contained by landmarks (19 elements)
