7. Why does the highest-share customize-checkout app differ from the #1 ranked app?
Rank reflects an app's current position in the Shopify App Store under customize-checkout (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 customize-checkout, TikTok leads on share; see the rankings tab for who currently holds #1 position.
