Is it necessary to collect data in advance to ensure that cross sellings are displayed to customers with good quality?

The plugin integrates four different types of cross sellings. These cross sellings behave as follows:

1. Customers also bought
The information is read directly from the orders already available in the system. No data collection is required here.

2. Products of the same category
The information is read dynamically via the category assignment. No data collection is required here.

3. Recently viewed
The data is collected as soon as the cross selling is activated. No data is collected beforehand.

4. Customers also viewed
The data is collected as soon as the cross selling is activated. No data is collected beforehand.
