Which built-in function in Google Analytics displays unexpected decreases or increases in your website traffic?

The anomaly detection function in Google Analytics is specifically designed to identify unusual spikes or dips in your website traffic and other metrics. It uses statistical algorithms to compare current data to historical patterns and flag deviations that fall outside expected ranges. This helps you quickly identify potential issues or opportunities. The machine learning function is a broader term encompassing various AI techniques, but "anomaly detection" is the specific function. Google AI is a general term for Google's artificial intelligence initiatives, not a specific GA feature for this purpose. The data-driven attribution function helps assign credit to different marketing touchpoints, which is unrelated to identifying traffic anomalies.
