To identify anomalies in your eCommerce conversion rates using BigQuery, you can leverage SQL queries to analyze historical data and detect deviations from expected patterns. This involves calculating baseline conversion rates and comparing them against current performance to spot unusual changes.

Example Concept: Use statistical methods such as standard deviation or moving averages in SQL queries to establish a baseline for normal conversion rates. By comparing current data against this baseline, you can identify significant deviations that may indicate anomalies. This approach helps in understanding whether changes in conversion rates are due to normal fluctuations or potential issues.

Additional Comment:

Ensure your BigQuery dataset includes relevant eCommerce data such as transactions, sessions, and user interactions.
Consider visualizing the results in Looker Studio for easier interpretation of anomalies.
Regularly update your baseline calculations to account for seasonal trends and changes in user behavior.
