What can result from incompatible targeting in DV360?

• A. Improved line item performance
• B. Reduced spend efficiency
• C. Enhanced audience reach
• D. Higher impression rates

Answer: (B)

Incompatible targeting in DV360 can lead to reduced spend efficiency. This situation arises when the targeting criteria set for a line item are too restrictive or do not align well with the available inventory. For instance, if the criteria selected greatly limit the audience or the type of placements that can be accessed, it will lead to under-delivery of impressions, thus wasting budget on line items that do not perform effectively. When spend efficiency decreases, it means that the spend does not translate into the desired outcomes, such as impressions or conversions, as the system has difficulty finding suitable inventory that meets the specified criteria.

In contrast, options that suggest improvements in line item performance, enhanced audience reach, or higher impression rates are typically related to optimal targeting practices, rather than those that are incompatible.
