Stackable and mutually exclusive rules

Stackable rules

You can stack multiple rules to the same ad, and the algorithm will execute the rule's action if it meets the trigger condition.

You can extend a Strategic Objective's behavior by assigning additional rules to an ad group.

In the above example, the ad group has a Strategic Objective containing 3 inherited bidding rules with a [Strategy] text besides their name.

The ad group also has 2 individually assigned rules; Bidding Rule 1 and Bidding Rule 4.

Algorithms will ignore duplicate rules and will not run the same rule twice.

The bidding algorithm will run Bidding Rule 1, Bidding Rule 2, Bidding Rule 3, and Bidding Rule 4 based on user-defined order of priority.

The algorithm will evaluate rules with higher priority over those with lower priority.

Mutually exclusive rules

You can only assign 1 rule to an ad.

For example, dayparting is mutually exclusive by nature; an ad can be paused or enabled from 1 am to 2 am.

An assigned rule takes priority over an inherited rule

You can overwrite a Strategic Objective's behavior by assigning a rule to the ad group.

In the above example, the ad group has a Strategic Objective with the dayparting rule Optimum Hours.

However, the ad group also has the dayparting rule Always Enabled.

The Always Enabled rule will supersede the one in Strategic Objective, striking off the inherited rule.

The table below shows the type for each algorithm.
