179 WooCommerce themes have Lighthouse scores as of 2026-09-15.

New themes are picked up from the marketplaces daily.
Does theme speed matter for a WooCommerce store?
Yes. Page speed is part of Google's ranking systems through Core Web Vitals, and slower pages convert fewer visitors. The theme sets the floor: apps, images and tracking scripts only add to what it loads. A theme that scores 90 or better on mobile on its own demo leaves room for a real store; one that scores 50 on an empty demo has none. Test your own store at /test-my-store.
How are WooCommerce themes tested for speed?
Each theme's own demo store is run through Google's PageSpeed Insights API (Lighthouse) on a simulated mobile phone and on desktop, for the home page and, on store platforms, a collection page and a product page. A theme's score is the median of its presets; a preset's is the mean of its pages. Dead, password-protected and cloaked demos are excluded before they can score. The full method is at /methodology.
