WooCommerce themes ranked by mobile SEO

On desktop, PeakShops by fuelthemes has the highest SEO score in September 2026 at 100 out of 100, then Ferrano at 100. Desktop scores run higher than mobile for the same theme because Lighthouse's mobile test simulates a mid-range phone on a slow 4G connection; mobile is the score Google ranks by.

181 WooCommerce 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.

Lighthouse's SEO score checks the technical basics a theme controls — crawlable links, meta tags, mobile viewport, legible fonts, valid structured markup — and most WooCommerce themes pass most of them, which is why SEO scores cluster high. Speed separates them: Google ranks on Core Web Vitals, so the best theme for rankings is one with a high SEO score and a high mobile speed score. PeakShops leads on SEO in September 2026; the speed ranking is one click away.

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.
