Prebid and Header Bidding: A Deep Dive into VAST and VPAID Tags

It has always been a difficult balancing act to maximize revenue while maintaining the best possible user experience in the ever-changing world of digital advertising. New tactics are developed as technology advances to assist publishers in striking this balance. These days, prebid and header bidding are two such tactics that have become very popular. We’ll go into these ideas and examine how VAST and VPAID tags work to maximize ad revenue in this article.

Understanding Prebid and Header Bidding

The innovative methods of header and prebid bidding have completely changed the way publishers offer their ad inventory. In the past, publishers used a waterfall model in which they provided ad impressions to many ad networks or exchanges in a sequential manner, beginning with the one that they liked. However, because this approach valued relationships more than actual bid values, it frequently resulted in inefficiencies and decreased revenue. On the other hand, before the page content loads, publishers can offer their ad inventory to several demand partners concurrently through prebid and header bidding, enabling advertisers to place real-time bids. The highest bidder finally wins in this transparent and equitable auction system, generating revenue for the publisher. Our area of expertise at Yield Maximizer ( is utilizing header and prebid bidding technologies to increase ad income for our clients. We guarantee the highest CPMs and fill rates by putting publishers in touch with a wide variety of demand partners, therefore optimizing income potential.

What VAST Tags Do

Delivering video advertising inside the prebid and header bidding architecture is made possible in large part by VAST (Video Ad Serving Template) tags. Video ad serving and display specifications are specified via VAST tags, which are XML templates. They have metadata including the length of the advertisement, the click-through URL, tracking pixels, and more.

VAST tags enable publishers to easily incorporate video advertising from various demand partners into their content while prebid and header bidding are in effect. The publisher’s ad server solicits bids from different demand partners when a user views a webpage including video ad inventory. After the bids are received, the user sees the video advertisement and receives the winning bid’s VAST tag.

With Yield Maximizer, publishers can be sure to work with a variety of excellent video demand partners who offer VAST tags that are tailored for optimum revenue and user engagement. Through effective partnership management and bid prioritization, we assist publishers in realizing the maximum value from their video ad inventory.

Looking Into VPAID Tags

While VPAID (Video Player Ad-Serving Interface Definition) tags take interactivity to the next level, VAST tags describe how video ads are served and displayed. By enabling marketers to develop interactive video ads with features like clickable overlays, interactive elements, and more, VPAID tags provide richer ad experiences. VPAID tags improve user experience in the prebid and header bidding ecosystem by offering interesting and interactive video ad content. Publishers can provide immersive ad experiences that capture viewers and increase engagement rates by utilizing VPAID tags. Leading ad networks and advertisers collaborate with Yield Maximizer to offer publishers VPAID tags that create engaging and dynamic video ad experiences. Our prebid and header bidding solutions now include VPAID tags, which helps publishers monetize their video inventory more efficiently while giving viewers interesting ad content.
