How does the priority value work when multiple offerings are eligible?
How does the priority value work when multiple offerings are eligible?
When multiple offerings are eligible to be displayed, a precise ranking system determines which one is selected. The evaluation follows a strict order of rules:
- First, the offering with the highest priority value is selected.
- If two or more offerings share the same priority value, the system evaluates their end dates and chooses the one with the earliest end date.
- If the end dates are also identical, the offering with the earliest start date takes precedence.
- In the rare case that the priority value, end date, and start date are all identical, one offering will be selected randomly from the eligible group.
