What key aspect does 'Smart Performance Campaign' (SPC) eliminate in performance campaigns?

The 'Smart Performance Campaign' (SPC) is designed to streamline and enhance performance campaigns by automating various processes that typically require manual intervention. By eliminating manual optimization of settings, the SPC leverages algorithmic capabilities to manage ad placements, bidding strategies, and ad creative optimizations in real-time based on performance data and user interactions. This automation not only saves advertisers time but also allows them to focus on strategic aspects of their marketing efforts, improving overall campaign efficiency and effectiveness.

The other choices, while relevant to campaign management, do not encapsulate the principal advantage of SPC as clearly as the elimination of manual optimization. Audience targeting requirements, the need for multiple ad groups, and setting budgets at the ad group level may still be components of the campaign structure; however, the significant shift introduced by SPC is the reduction of the advertiser's hands-on involvement in optimizing campaign parameters. This change represents a broader movement toward automation in digital advertising, where data-driven decisions can enhance performance without necessitating constant manual adjustments.
