Trending

The biggest changes in mobile SEO between a theme's latest test and its last test at least a week earlier. A move of 3 points or more counts; Lighthouse varies by a point or two between runs.

Not enough re-tests yet: trending needs a theme measured at least a week apart, and the score history began on 2026-09-11. This section fills in as themes are re-measured.

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.
