Which option is not a feature of the TikTok Ads Manager?

The choice identified as not a feature of the TikTok Ads Manager is indeed correct, as Public Relations is not a functionality offered within this platform. TikTok Ads Manager is specifically designed to assist advertisers in creating, managing, and optimizing advertising campaigns.

Features such as Campaign, Analytics, and Tools are integral components of the Ads Manager. The Campaign feature allows users to set up and organize their advertising efforts. The Analytics feature provides insights into the performance of campaigns, allowing for data-driven decision-making. Tools encompass various functionalities that support campaign management and optimization processes, including ad creation and targeting capabilities.

Thus, the absence of Public Relations emphasizes TikTok Ads Manager's focused functionality on advertising rather than broader marketing or PR strategies.
