Which of the following is NOT true about digital advertising?

Digital advertising is characterized by its reliance on various online strategies and technologies that enable marketers to reach consumers where they are most active—on the internet. Among the key aspects of digital advertising are programmatic advertising, which automates the buying and selling of online ads; the ability to track users' online behavior to craft targeted marketing messages; and commonly employing models such as pay-per-click (PPC), which allows advertisers to only pay when users interact with their ads.

The assertion that digital advertising requires a physical presence for effective targeting is inaccurate. In fact, one of the primary advantages of digital advertising is its capability to target specific audiences without any need for physical interactions or locations. Marketers can tailor their advertising efforts based on online data and analytics, allowing them to reach customers based on their digital behavior rather than their geographical presence, thus making option D not true in the context of digital advertising.
