Which is a known limitation of Google Analytics?

Google Analytics has certain limitations, and one of the well-documented issues is related to sampling limits and potential tracking inaccuracies. When a user has a large volume of data, Google Analytics may sample the data to improve performance and speed up reporting. This means that not all data points are processed, potentially leading to less precise insights, especially for large datasets or specific segments of traffic. The sampling threshold can affect the accuracy of reports and user behavior analysis, which is particularly concerning for businesses that rely on precise data for decision-making.

The other options reflect features or characteristics of Google Analytics rather than limitations. For example, the ability to provide real-time data analysis showcases a strength of the platform, while compliance with data privacy laws is more about how the tool is utilized rather than an inherent limitation of the software itself. Tracking mobile app downloads is a capability of Google Analytics, but it is not considered a limitation.
