What does "viewable page" refer to in electronic media advertising?

In the context of electronic media advertising, a "viewable page" refers to a page that can be experienced as a separate unit. This definition emphasizes the ability for users to interact with and process the content on that page independently. It implies that the page is designed in a way that it effectively captures attention and communicates its message without needing to scroll or navigate away, allowing it to be experienced as a distinct entity.

The other options do not accurately define what a viewable page is. A page that may scroll beyond the screen borders, for example, does not provide the same clear and separate experience because users must engage in additional actions to access the content. Additionally, a page that cannot be viewed on mobile devices is not relevant to the concept of viewability, as this pertains to accessibility rather than user experience. Finally, a page that does not require internet access speaks to the offline availability of content but does not address the concept of how users experience and interact with that content on electronic media.
