There are two types of optimization. What are they? Choose two.

Media mix optimization involves strategically allocating your advertising budget across various channels and platforms (like search, social, display, video) to achieve the best overall campaign performance. It focuses on finding the right balance of investment across different media types. Channel optimization, on the other hand, refines the performance within a specific advertising channel. For example, optimizing your Google Search campaigns by adjusting keywords, ad copy, or bidding strategies within that particular channel. While bidding optimization and targeting optimization are crucial aspects of campaign management, they are generally considered tactics within a channel or media mix, rather than distinct types of optimization at the broader strategic level.
