How does a roadblock ad differ from an interstitial ad?

The correct answer highlights that a roadblock ad occurs before the first page of content. This distinction is crucial for understanding the user experience associated with different types of ads.

In digital advertising, a roadblock ad is designed to dominate the ad space on a webpage, often shown across multiple pages of a site or across a network of sites at the same time. This results in the user encountering this type of ad prominently before they access the main content. The intention behind roadblock advertising is to ensure maximum visibility and exposure of the ad to the user right at the beginning of their browsing session.

By comparison, other types of ads, such as interstitial ads, are also placed before or during content but are usually displayed in a way that interrupts the user’s experience just as they are trying to engage with the site. While interstitials appear before any page content, the emphasis for roadblock ads is their integrated approach over multiple pages.

Understanding this differentiation helps advertisers and digital marketers strategize better placements and expectations for user interaction, ultimately shaping how campaigns are designed and executed.
