Page views
Page views breaks your in-app traffic down per path: how many views each page got, how many distinct shops visited it, and each page’s share of the total.
Use it to find where merchants actually spend time. A settings page outranking your core feature usually means friction; a feature page nobody visits usually means a discovery problem, not a quality problem.
Data comes from the same page_view events as web analytics; if that page has numbers, this one does too.
