What are the two types of optimisation? Choose two.

Media mix optimization involves allocating budget across different advertising channels (e.g., TV, digital, print) to maximize overall campaign performance. This ensures that resources are distributed effectively where they will have the greatest impact. Channel optimization, a more granular approach, focuses on improving performance within a specific advertising channel. This could involve refining ad creatives, adjusting bidding strategies, or optimizing targeting settings for a particular platform like Google Ads or Facebook. Bidding optimization is a component of channel optimization, not a separate type of optimization. Targeting optimization is also a component of channel optimization, focusing on audience refinement.
