Final answer:
The First Interaction model is the attribution model that would be useful for evaluating ads and campaigns designed to create initial awareness about a brand.
Step-by-step explanation:
The attribution model that would be useful for evaluating ads and campaigns that are designed to create initial awareness about a brand is the First Interaction model.
The First Interaction model gives credit to the first touchpoint or interaction that a user has with an ad or campaign. In the context of creating initial awareness about a brand, this model helps track and analyze the effectiveness of the first ad or campaign that catches the attention of potential customers and introduces them to the brand.
For example, if a user sees an ad on social media that raises awareness of a brand for the first time and later converts into a customer, the First Interaction model would attribute the conversion to that first ad.
