2. How are sizing Shopify apps ranked?
Rankings on this page reflect each app's position in Shopify's keyword search results for "sizing", which Shopify computes from a mix of merchant install volume, review velocity, and recency.

7. Why don't apps ranked beyond #22 show market share for sizing?
For keyword pages, market share is rank-weighted: position #1 carries roughly 40× the weight of position #22, and apps beyond #22 receive zero weight. This reflects Shopify search behaviour — merchants almost never scroll past the top of the results, so positions further down don't translate to installs.
