If you need to pick the two types of optimization, which ones would you choose? Choose two.

The two types of optimization are Channel optimization and Media mix optimization. Channel optimization focuses on improving the performance within a specific advertising channel (e.g., Google Search, Display Network) by adjusting elements like keywords, ad copy, and audience targeting. Media mix optimization, on the other hand, involves strategically allocating budget across different advertising channels and media types to achieve the best overall campaign performance and return on investment. Targeting optimization is a component of channel optimization, not a separate type of optimization. Bidding optimization is also a component of channel optimization, focusing on bid strategies within a channel.
