A roadblock ad is a type of digital advertising that takes over an entire webpage or app, blocking the user's access to the content until the ad has been viewed or interacted with. Roadblock ads are typically used to drive maximum visibility and attention for a brand or product, and they are often used for high-profile launches or events.

Roadblock ads can be effective at driving engagement and conversions, but they can also be seen as intrusive by users and may lead to negative reactions and introduction of ad blockers if they are not implemented carefully. Advertisers should consider the user experience and the potential impact on brand perception when using roadblock ads.

There are different types of roadblock ads, including:

• Full-page interstitial ads: These are ads that take up the entire screen of a website or app and require the user to interact with them before they can access the content.

• Video roadblock ads: These are ads that take over a video player and require the user to watch the ad before the video content can be accessed.

Roadblock ads can be served through a variety of ad servers and are typically managed by specialized teams or agencies.
