Vast VS VPaid In 2024

Vast VS VPaid In 2023:

Did you know the difference between Vast and Vpaid? If not, then in this guide, I’ll tell you the main difference between vast and vpaid and what these terms mean.

Recognizing the distinctions between the VAST and VPAID advertising protocols have never been more crucial given the increase in the usage of video content. By 2022, online streaming traffic—up 9 percent from 2017—is anticipated to account for 82% of all consumer web traffic.

Individuals are choosing video over textual information and audio content in growing numbers, showing digital marketers that investment in video advertising is the right move if they wish to increase their return on investment. This is by no means a recent development; studies conducted more than ten years ago found that including videos in emails increased click-through rates (CTRs) for marketers by 200–300%.

For authors as well as marketers, technologies, including VAST and VPAID, play a crucial part in digital advertising. In-stream video advertisements were introduced by the IAB (Interactive Advertising Bureau) as a component of the IAB Video Suite to support the streaming video business. To better grasp the VAST and VPAID scripts’ significance for your publisher ad stack, we’ll examine them in more detail in this piece.

What exactly is VAST?

The “Video Ad Serving Template,” or VAST, seems to be an XML format that HTML 5 players and advertisement providers utilize to offer video adverts. By utilizing VAST, marketers may control the video player advertising and configure certain details like:

  • What commercial should be aired?
  • Whether it is feasible to ignore an advertisement and when the user may do so;
  • The placement of the advertising throughout the video content
  • Just after CTA, what tends to happen? (call to action)
  • VAST functions on various platforms and settings, including desktop, mobile, tablet, online, and in-app.

How does VAST function?

A video player requests that an ad be shown by requesting an ad server, which is the beginning of the fundamental flow of the VAST tag. The advertisement reacts by producing VAST tags for the video formats; these are responsible for several aspects, such as rendering advertising, selecting the type of media used for an advertisement, its duration and format, tracking and price data, and much more.

What Exactly is VPAID?

The video player-ad interface, or VPAID, is a form of advertising software that works with VAST (Video Ad Serving Template). VPAID creates a standardized interface among video players as well as advertising servers. While VPAID enables marketers and publishers to provide a rich media, interactive ad experience, VAST was designed to provide linear advertising with minimal interaction.

In addition to enabling a rich media advertising experience and collecting statistics on ad player and user engagement, VPAID saved expenditures that would have been incurred due to VAST’s feature limitations. With VPAID, there is less need for additional technology and a faster translation of the language of advertising servers to the programming language of video players. In consequence, advertisers may grow and manage their marketing initiatives.

Additionally, pre-roll features are available for viewers to engage in to learn more. Additionally, VPAID tags are integrated with location features so that viewers in various locations can see various advertising (companion and overlay).

VPAID technology employs tags to measure metrics, including viewability, CTR, and completion percentage. A transparent overlay is applied to the video to track usage and outcomes. As a result, new possibilities for ad development and optimization are made possible for advertisers, who can now monitor their progress and observe how viewers react to their advertising.

Why is it crucial for marketers?

The benefit of VPAID is that it allows you to track how each ad is doing and develop new strategies for engaging your audience and boosting ad engagement. A consumer might click on an advertisement to watch additional in-depth material, such as a lengthier pre-roll, as an example of an interaction made possible by VPAID.

With the standard play, stop, close, and hide buttons and other options, you may decide when and where the advertisement is displayed inside the video. The user’s actions will be noted and reported to the marketer.

Main Differences Between VAST and VPAID:

There are differences between the two in the way that adverts are served:

1- Function:

A video file is retrieved and played in VAST through the OVP (Online Video Platform). The OVP retrieves a dynamic code in VPAID but not in OVP. The player’s visible region is under the command of this coding. The OVP receives the controls back when the video advertisement has finished playing.

2- Viewability:

The VAST tag asks the browser’s intersection monitor API for information to confirm viewability, and the intersection viewer API returns the information. In contrast, in VPAID, the tag regains the command of the video player before loading JavaScript in the browser to collect viewability information.

3- Limitation:

VPAID permits the preloading of an ad unit before rendering the ad media, whereas VAST prohibits it.

4- Exchanging data:

VPAID focuses on enabling the distribution of sophisticated advertising, while VAST emphasizes the standard method that data is exchanged between systems.

5- The power to direct the player:

Publishers have greater influence over the player when VAST operates well, but purchasers have more power when the VPAID protocol is used.

6- Fourth Version:

IAB is now working on the fourth iteration of VAST, which is intended to take the place of VPAID. Work is being done to enable VAST to measure viewability and advertisement confirmation. However, as the past demonstrates, the industry needs to be more active in implementing VAST. It’s common to find publishers utilizing video players that are version 2 or 3 even after version 4 was published.

Pros and Cons of VAST:


  • The industry uses it extensively as a universal format.
  • Most recent iterations offer minimal interaction.
  • The method of submitting an ad request is standardized.
  • It makes the interaction between the video player and the advertisement server easier.
  • Publishers have a better potential to expand operations and offer more digital advertising space thanks to VAST.


  • The older version of VAST didn’t implement viewability standards.
  • The chances for admeasuring, preloading and support for interactivity are less available with VAST than with VPAID.
  • small capacity
  • uncontrolled quality
  • Supports none of the criteria for broad industry visibility.
  • The vast majority of publishers still need to embrace VAST 4.0 and above.

Pros and Cons of VPAID:


  • Enables easy performance measurement of interactive ad units and supports them well.
  • It may result in greater yields for publishers because there is an opportunity to support different kinds of video advertisements.
  • Call-to-action overlays and other interactive elements (CTAs)
  • Provision of programmatic advertisements
  • increased demand for video inventory
  • The user experience is improved through interactive advertisements.


  • VPAID has the potential to slow websites down under certain conditions.
  • Although less accommodating for other situations, the standard is suitable for mobile.
  • Issues with privacy as well as compatibility
  • Issues with faith and transparency
  • In mobile applications and CTVs, VPAID has terrible performance.
  • It may make invasive player features like sound available for smartphones.

Frequently Asked Questions (FAQs):

Is Vpaid a tag for VAST?

Answer: The delivery of inline creative types to video players is the main objective of this advertisement template. Whenever VPAID is stacked with VAST, the IAB delivery and third-party video player interaction standards are inherited. Ads should be supported by VPAID standards and VAST for them to appear on the video player.

How do VAST tags work?

Answer: A player accesses video and audio adverts through a VAST ad tag URL. Utilizing the settings listed here, you may manually put together a VAST ad tag URL or alter an already-existing URL, then evaluate it using the VAST suite analyzer. Utilizing these sample tags, you may study and evaluate. HTTP and HTTPS are both supported by VAST ad tags.

What exactly is a Vpaid creator?

Answer: A rich multimedia creative called VPAID is sent as an extra media asset type inside a VAST tag. The in-stream video player of a publisher frequently uses VPAID for interactive advertising. The video player may be muted or paused by VPAID creatives, which can display their material, including interactive features.

What distinguishes VAST from VMAP?

Answer: You may place a VAST commercial as just a pre-roll, mid-roll, and post-roll within a single ad interval. A VMAP advertising is a playlist of ad breaks that may include any number of pre-rolls, mid-rolls, and post-rolls.

What exactly is the VAST wrapper?

Answer: A VAST instance that serves a VAST advertisement by rerouting traffic to some other URL. Along with the VAST ad monitoring URLs, the wrapper is also allowed to have its unique tracking URLs that are pingable. If the wrapped VAST cannot provide an ad, the wrapper may also offer backup creatives for display.

Final Thoughts:

Recognizing the advantages and shortcomings of VAST and VPAID is the first approach to the complex world of video advertising in general and ad serving in particular. Then, to provide a seamless experience for your visitors, aid advertisers in scaling the delivery of their campaigns, and expand your income potential, it’s imperative to maintain compliance with any of the standards.
