Which BigCommerce theme is best for Google rankings?
Lighthouse's SEO score checks the technical basics a theme controls — crawlable links, meta tags, mobile viewport, legible fonts, valid structured markup — and most BigCommerce 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. Tribes Automotive leads on SEO in September 2026; the speed ranking is one click away.
How are BigCommerce themes tested for SEO?
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.
