Which of the following is NOT a main component of a typical digital analytics implementation?

In a typical digital analytics implementation, the main components are focused on the lifecycle of data from collection to presentation. Data collection involves gathering data from various sources like websites, mobile apps, and other digital platforms. Data processing includes cleaning and structuring this data so it can be useful for analysis. Data visualization is essential for presenting the processed data in a way that stakeholders can understand and derive insights from it.

User engagement tracking, while valuable, is not considered a main component of digital analytics implementation. Instead, it falls under the broader category of data collection, as it specifically focuses on how users interact with digital properties. This makes it a specific facet of data tracking rather than a standalone component like the others mentioned. Thus, it does not match the critical components of an analytics framework, which are primarily centered around how data is gathered, processed, and visualized for decision-making.
