What are ad slots?

Ad slots refer to designated spaces within a website or app specifically allocated for the display of advertisements. This concept is central to programmatic advertising, as it allows publishers to manage where ads appear on their platforms and helps advertisers identify suitable placements for their campaigns. Each ad slot can be programmed with specific parameters, such as size, format, and the type of ads it can display, making it essential for maximizing ad effectiveness and ensuring a good user experience.

The other options, while related to advertising in general, do not accurately describe ad slots. For instance, predetermined delivery times for ads are more aligned with scheduling advertising campaigns rather than the physical placement of ads, and areas dedicated to collecting user interactions focus on analytics rather than the ad placement itself. Additionally, restricted locations refer to areas where ads cannot appear, which is opposite to the concept of ad slots, where placements are actively managed and specified.
