Integrating Google Analytics (GA) with Facebook Mobile Ads can improve your campaign tracking. First, you need to set up Google Analytics for your mobile app. Ensure you have an active GA property and tracking ID. In your Facebook Ads Manager, add UTM parameters to your ad URLs. These parameters help GA track clicks, sessions, and conversions from Facebook ads. Use the GA dashboard to analyze data, including user behavior and ROI. You can also set custom goals in GA to measure specific actions. Integrating GA helps you understand your audience and optimize Facebook Mobile Ads for better results.
