martello-coffee.com website review

About 291 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.5 s faster on a phone.

A phone's processor spends 4.9 s on main-thread work while loading, 2.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (iubenda, Google Tag Manager and Shopify and others), adding 1.1 MB and 1.3 s of main-thread time.

Your mobile performance score is 51. Pages that score under 90 lose visitors before the first paint.

10 files are served with short cache lifetimes, so returning visitors download them again (113 KiB).

iubenda costs a phone 523 ms of main-thread work and 121 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.

Google Tag Manager costs a phone 384 ms of main-thread work and 349 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 costs a phone 305 ms of main-thread work and 502 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.

9 long tasks block the main thread while loading, the longest for 286 ms. During a long task the page ignores taps.

3 KiB could be saved by minifying JavaScript.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

About 38 KiB of CSS is downloaded but never applied on this page.

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