The impact of a given delivery modifier rule is dependent on (a) the amount of supply the rule applies to (b) the magnitude of the rule. For this reason, we suggest adjusting delivery modifiers in an iterative fashion so that the supply makeup is indexing indexes as desired, but that pacing isn’t overly impacted more than desired.
Delivery modifier rules should initially be set at a value close to 1.0 (ie. 0.8 - 1.3). Delivery should be assessed with these initial values.
If delivery matches desired outcome then no adjustments are needed
If delivery does not match desired outcome then increase/decrease modifier rules as needed
