About this report
Scores are Google Lighthouse SEO scores from the PageSpeed Insights API, run against each theme's own demo store — the home page and, on store platforms, a collection and a product page — on a simulated mid-range phone and on desktop. A theme's score is the median of its presets; a preset's is the mean of its pages. Every run is kept, and a theme's page shows its history. This month's report updates daily until the month ends.
