Google PageSpeed Insights (opens in a new tab), mobile
One score from every part of this review. How it works
Speed
Mobile performance score: 72
72/100Your mobile performance score is 72. Pages that score under 90 lose visitors before the first paint.
Improve image delivery
552 KiB20 images could be 552 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.
Reduce unused JavaScript
170 ms · 35 KiBAbout 35 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 170 ms faster on a phone.
1 long task on the main thread
1 long task block the main thread while loading, the longest for 72 ms. During a long task the page ignores taps.
2 third-party services on the page
2 third-party services load with your homepage (Shopify and shop.app), adding 119 KiB and 31 ms of main-thread time.
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.
Use efficient cache lifetimes
1 KiB1 file is served with short cache lifetimes, so returning visitors download them again (1 KiB).

Main-thread work: 0.8 s
A phone's processor spends 0.8 s on main-thread work while loading, 246 ms of it running JavaScript. That is comfortably low.
Server response: 6 ms
6 msYour server sent the HTML in 6 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Largest Contentful Paint: 6.4 s
6.4 sYour largest element takes 6.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Backstage in New York”.
Time to Interactive: 6.7 s
6.7 sThe page becomes fully interactive after 6.7 s. Good is under 3.8 s.
Speed Index: 5.0 s
5.0 sVisually, the page fills in at 5.0 s (Speed Index). Good is under 3.4 s.
First Contentful Paint: 2.0 s
2.0 sThe first text or image appears after 2.0 s on a phone. Good is under 1.8 s.
Not enough real-visitor data yet
Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.
2 checks passed
Cumulative Layout Shift: 0
0The layout barely moves while loading (CLS 0, good is under 0.1).
Total Blocking Time: 22 ms
22 msScripts block the page for only 22 ms while loading. Good is under 200 ms.
Images and page weight
Page weight: 2.1 MB in 156 requests
2.1 MBYour homepage downloads 2.1 MB in 156 requests on a phone: images 1.1 MB (25), other files 669 KiB (68) and scripts 210 KiB (39). Under 2 MB keeps phones on slow connections fast.
3 images in older formats
3 images (203 KiB) 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 0.6 g of CO₂ per visit
0.59 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.59 g of CO₂e: 71.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
