If your Looker Studio dashboard shows different numbers than GA4, the root cause usually lies in different data models. Furthermore, GA4 and Looker Studio use distinct sampling methods, which lead to divergent results. Additionally, the selected date range plays a crucial role. In this article, we explain why your Looker Studio dashboard shows different values and how to fix the discrepancies.

Why Does the Looker Studio Dashboard Show Different Numbers Than GA4?

First of all, the differences are often based on data sampling. When your Looker Studio dashboard shows different numbers than GA4, Looker Studio accesses a data sample rather than processing all data points. Moreover, differing date filters or timezone settings can influence the results. Therefore, you should first check whether both tools use the same date range.
