Which of the following is NOT a type of campaign experiment?

Market research methods are not considered a type of campaign experiment in the context of digital advertising and performance campaigns. Campaign experiments typically focus on actionable strategies within campaigns themselves, such as bidding strategies, creative testing, and targeting strategies, all of which are integral to optimizing ad performance and measuring results.

Bidding strategies refer to the different approaches advertisers can take to allocate their budget effectively, which can significantly affect the performance of their advertising campaigns. Creative testing involves experimenting with various ad creatives to determine which designs, messaging, and formats resonate best with the target audience. Targeting strategies concern the methods used to reach specific audiences based on demographics, behaviors, or interests.

On the other hand, market research methods involve gathering data and insights about market conditions, consumer preferences, and competitive dynamics, which, while beneficial, do not directly constitute a campaign experiment focused on improving the performance of an existing campaign. Instead, market research serves to inform future campaign decisions rather than participating in the experimental process of current campaign execution.
