What are the three types of tags mentioned in programmatic advertising?

The option identifying the three types of tags in programmatic advertising as image pixel, iFrame, and JavaScript tags is accurate because it reflects the common mechanisms used to implement tracking and ad serving functionalities.

Image pixel tags are small snippets of code that allow advertisers to track user behavior by loading a transparent image when a page is viewed. This is crucial for performance tracking and retargeting efforts.

iFrame tags create a separate browsing context within a page, enabling the loading of ads or content from different sources without directly modifying the parent page. This is specifically useful for ensuring that advertisements can be displayed seamlessly and securely.

JavaScript tags are versatile scripts that allow for more complex interactions and functionalities, such as ad tracking, executing dynamic content, and integrating with various advertising technologies. They enable real-time data processing and interaction with user actions on a webpage.

These three types of tags are essential in programmatic advertising for performance measurement, user interaction tracking, and ad delivery optimization, making this option the correct one. The other options do not accurately represent the tags commonly employed in programmatic advertising.
