Comparison of VAST & VPAID

By December 13, 2023No Comments

In the world of online advertising, video has become an increasingly popular format for engaging audiences. With the rise of video advertising, two essential standards have emerged: VAST (Video Ad Serving Template) and VPAID (Video Player-Ad Interface Definition). These standards play a crucial role in delivering and interacting with video ads, but they serve different purposes and offer distinct functionalities. In this article, we will delve into what VAST and VPAID are, how they work, and the key differences between them.

Video Ad Serving Template (VAST)

Simplifying Video Ad Delivery VAST, or Video Ad Serving Template, is a standard XML-based format developed by the Interactive Advertising Bureau (IAB). Its primary purpose is to simplify the delivery of video ads across different video players and platforms. VAST standardizes how video ads are packaged and transmitted, ensuring compatibility and ease of integration between advertisers, publishers, and ad networks.

How VAST Works

  • Advertiser creates a video ad and associates it with a VAST URL or XML file.
  • The VAST file contains information about the ad, such as its duration, target audience, tracking URLs, and media files (e.g., video, audio, and images).
  • Publishers and ad networks integrate VAST-compatible video players on their websites or apps.
  • When a video player loads a video content page, it requests a VAST file from the ad server.
  • The ad server responds with the VAST XML, which the video player interprets and displays accordingly.
  • The video player retrieves the media files specified in the VAST file and plays the ad to the viewer.
  • VAST provides a standardized way for ad servers to communicate with video players, enabling dynamic ad insertion, tracking, and targeting capabilities. It allows publishers to monetize their video content by easily integrating video ads from various advertisers and networks.

Video Player-Ad Interface Definition (VPAID)

Enhancing Interactive Video Ads While VAST focuses on ad delivery, VPAID, or Video Player-Ad Interface Definition, is an additional standard that enhances the interactivity and functionality of video ads. VPAID is built on top of VAST and enables ad interaction, data tracking, and dynamic ad changes within the video player itself.

How VPAID Works

  • Advertiser creates an interactive video ad that conforms to the VPAID specification.
  • The VPAID ad is associated with a VAST file that includes a reference to the VPAID script.
  • When the video player receives the VAST file, it detects the presence of a VPAID ad and loads the associated VPAID script.
  • The VPAID script establishes communication between the video player and the ad, allowing for interactions and data exchange.
  • The VPAID ad can then display interactive elements, respond to user interactions, and request additional tracking or reporting data from the video player.
  • The video player handles the user interactions and communicates the results back to the VPAID ad.
    VPAID enables a range of interactive ad experiences, such as clickable overlays, interactive games, quizzes, and dynamic ad elements. It provides a standardized interface for video players and ads to communicate, enhancing the engagement and effectiveness of video advertising campaigns.

In summary, VAST and VPAID are two essential standards in video advertising that serve different purposes. VAST focuses on ad delivery and compatibility, while VPAID enhances interactivity and functionality within the video player. By understanding the distinctions between these standards, advertisers, publishers, and ad networks can optimize their video ad campaigns and deliver engaging experiences to their audiences.

Which Tag Is Better, VAST or VPAID?

The choice between VAST and VPAID depends on the publisher’s specific needs and goals. If a publisher desires a more interactive and engaging ad experience for their audience, VPAID may be the preferred option. However, it’s important to carefully consider the trade-off between interactivity and security. VAST, being a widely adopted standard, provides simplicity and compatibility, making it a suitable choice for delivering video ads across different platforms.

Ultimately, the decision between VAST and VPAID should be based on factors such as desired interactivity, security considerations, compatibility with video players, and the overall objectives of the advertising campaign.
