What key capability difference distinguishes Expert mode from Smart mode?

Expert mode offers more advanced features and control compared to Smart mode. A key differentiator is its ability to access additional inventory sources, such as Twitch and Amazon's Online Video inventory, through Amazon DSP (Demand-Side Platform). This expanded reach allows advertisers to target a broader audience beyond Amazon's owned and operated sites. Smart mode, while user-friendly, focuses on automated campaign optimization within Amazon's core advertising placements. Expert mode does not inherently simplify workflows; rather, it provides more granular control, which can be more complex. It also doesn't necessarily offer lower minimum spend requirements; in fact, the advanced capabilities might be associated with higher budget recommendations.
