Ingrid's client is the online sporting goods retailer, Sports Gear. What is a key factor of their business that will influence how Ingrid determines their mobile tracking strategy?

The existence of a mobile app for both iOS and Android is a key factor because it introduces the need to track in-app conversions, user engagement within the app, and potentially deep linking from ads directly into the app. This significantly impacts the mobile tracking strategy, requiring SDK integrations and specific app analytics tools in addition to website tracking. "Sports Gear does not sell snowboards" is irrelevant to tracking strategy. "The Sports Gear website looks great on large desktop screens" describes desktop experience, not mobile, and doesn't impact tracking strategy. "Sports Gear's research has shown that their customers also enjoy good coffee" is an unrelated demographic insight that does not influence mobile tracking.
