Every check is your own figure against the median of the apps at the top of your category page — real positions, not our ranking. Free, and no account.
Any of the 29,000+ Shopify apps we track.
How many your gallery has, against the median of the apps above you on your category page.
Whether your price is visible at all, and how your meta description (the line Google shows in web search) compares to the ones winning the page.
Rating and review count as context — shown, but never counted as something to fix this week.
Where we hold no figure for a listing, the scorecard says so rather than scoring it zero. A check we could not make is never counted against you.
