How many ecommerce themes have been tested, and how often are the scores updated?
15,663 ecommerce themes have Lighthouse scores as of 2026-09-15. Every theme is re-tested on a schedule set by its popularity — the most used every week, the long tail every one to two months — and every run is kept, so a theme's page shows its history. New themes are picked up from the marketplaces daily.
Does theme speed matter for an ecommerce 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 ecommerce 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.
