Add GA4 in order to monitor traffic behavior

Integrating Google Analytics 4 (GA4) will give us deep visibility into how both developers and users navigate our marketplace platform. By tracking user journeys, page interactions, conversion funnels, and engagement patterns, we can identify friction points in the onboarding process, understand which app categories drive the most interest, and optimize the search and discovery experience. This data-driven approach will help us make informed decisions to improve conversion rates, reduce bounce rates, and ultimately support our goal of reaching 10 million active users while maintaining high satisfaction scores.
