|Amplitude provides multiple options to customers to help manage the quality of their data.
For instance, Schema contains the definition of the events, event properties, and event properties’ values collected by Amplitude. Use it to categorize and describe your event data, as well as automate the QA process for newly ingested data by surfacing or blocking unintended or malformed data.
The Govern feature gives you multiple ways to manage your Amplitude data from within a single interface. Govern gives you the tools to conduct data management at scale, including bulk event approval, blocking, deletion, and un-deletion directly from the user interface.
|Google Analytics 4 provides best practices around account structure to help you manage data collected. This data can be controlled with the Custom Reporting features so that you can focus teams around sets of data; however, it is unclear if GA4 provides a way to prevent collection of events that are unexpected or incorrectly instrumented, which could count against your collection limits and negatively impact your reports, audiences, or marketing workflows.
Data quality in GA4 is limited to the provided DebugView and an organization’s analytics QA processes when instrumenting.
Users have noted some data quality issues with GA4, such as a bug that reported event names as an empty value and data inconsistency issues.
