What percentage of all digital advertising is conducted through machine-to-machine communication?

The correct answer reflects the increasing role that automated systems play in the digital advertising landscape. Machine-to-machine communication refers to the automated exchanges of data between systems, often in real-time, enabling advertisers to optimize their campaigns more efficiently and effectively.

The correct percentage signifies that a significant portion of digital advertising transactions is now occurring autonomously, minimizing the need for human intervention in processes such as bidding, targeting, and analytics. This automation is fueled by advancements in technology, data analytics, and artificial intelligence, allowing for more dynamic and responsive marketing strategies.

In this context, the other percentages do not accurately represent the extent of machine-to-machine communication in digital advertising today. The figure indicates a balance between fully automated processes and traditional methods still reliant on human input, which continues to evolve as the industry advances. Therefore, the choice provided as the correct option encapsulates the trend of growing dependency on automation in digital marketing.
