2. How is market share calculated for cross sell Shopify apps?

7. Why does the highest-share cross sell app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under cross sell (driven by Shopify's own algorithm), while market share on ShopDigest is estimated from review counts and other factors as a proxy for active installs. The two metrics move on independent dynamics, so the highest-share app and the #1-ranked app are not always the same — and a divergence between them is worth noting rather than assuming one will pull the other along. For cross sell, Kaching Bundles App & Upsells leads on share; see the rankings tab for who currently holds #1 position.
