Expression
Expression is a Shopify theme by Clean Canvas ($220). Tested on 2026-11-08 with Google Lighthouse via PageSpeed Insights on its own demo store, it scores 77 for mobile speed and 96 for desktop speed, 61/61 for SEO and 91/91 for accessibility (mobile/desktop, 0–100). Those are medians across its 4 tested presets; mobile speed across every tested page ranges from 72 to 87. On its marketplace it is rated 4.6 out of 5 from 71 reviews. Note: its demo home page is heavy — 9.4 MB — heavier than a typical store, so the speed score may understate the theme.
