Data discrepancies between Google Ads and GA4

Data discrepancies between Google Ads and Google Analytics 4 (GA4) can arise due to several factors:

1. Attribution models: Google Ads uses a last-click attribution model by default, crediting the last touchpoint before conversion. GA4 offers various attribution models, including data-driven attribution, which distributes credit across multiple touchpoints. This fundamental difference can lead to varying conversion counts.

3. Clicks vs. sessions: Google Ads focuses on clicks, while GA4 tracks sessions. If a user leaves and returns within a short period, a single click in Google Ads can result in multiple sessions in GA4, leading to different reporting figures.
4. User identification: GA4’s user-centric approach may track users across devices, while Google Ads might not, especially if users are not signed in to their Google accounts on all devices.
5. Filters and data processing: GA4 may apply filters or processing rules that exclude specific data, whereas Google Ads might include all clicks, leading to discrepancies in reported metrics.
6. Timing differences: Due to processing times, data reporting can lag between the platforms, especially with GA4’s more complex event-based model.
