Dayparting Rule Priority Logic
Dayparting allows advertisers to create multiple rules that adjust advertising behavior during different time periods. Because multiple rules may exist within the same configuration, it is possible for two or more rules to apply to overlapping time windows.
When this occurs, the system must determine which rule should take precedence. This is managed through rule priority.
Rule priority determines the order in which Dayparting rules are evaluated and applied.
Why rule priority matters
In many advertising setups, multiple rules may affect similar time windows or performance conditions.
For example, an advertiser may create:
- a rule that reduces bids during late-night hours
- another rule that increases bids during certain promotional periods
If both rules apply to the same time slot, the system must decide which rule should be executed.
Without a priority system, these rules could conflict with each other and produce inconsistent results.
How rule priority works
Each Dayparting rule is assigned a priority level that determines its execution order.
Rules with higher priority are applied before rules with lower priority.
If multiple rules apply to the same time period, the system evaluates them according to their priority ranking.
The rule with the highest priority will determine the final adjustment applied to the campaign.
Priority indicators
Within the Dayparting interface, rule priority is visually represented using star indicators.
Rules with more stars represent higher priority levels.
For example:
- a rule with five stars represents a higher priority rule
- a rule with fewer stars represents a lower priority rule
This visual system helps advertisers easily understand which rules will take precedence when multiple rules overlap.
Adjusting rule priority
Advertisers can adjust rule priority directly within the Dayparting rule list.
Rules can be reordered to ensure that the most important rules are evaluated first.
Changing the order of rules allows advertisers to control which adjustments should take precedence when conflicts occur.
Example rule conflict
Consider the following scenario:
Rule A:
- IF Time = 02:00–06:00
THEN Decrease Bid
Rule B:
- IF Time = 02:00–06:00
THEN Increase Bid
If both rules apply to the same time window, the system must determine which adjustment to apply.
- If Rule A has higher priority, the bid will decrease during those hours.
- If Rule B has higher priority, the bid will increase instead.
Because of this, rule priority ensures that Dayparting behavior remains predictable even when multiple rules affect the same time periods.
