JuliaOne of the most transformative innovations in the digital advertising domain is the advent of real-time bidding (RTB), facilitated by the Open Real-Time Bidding (OpenRTB) protocol. This technology has revolutionized the way ad impressions are bought and sold, offering unprecedented efficiency, transparency, and access to a vast pool of advertisers.
Today, the PubCircle experts will discuss the essentials of OpenRTB and its pivotal role in streamlining programmatic advertising. We will explore how this standardized protocol empowers publishers to unlock their digital advertising potential and foster a competitive marketplace. By understanding the mechanics and benefits of OpenRTB, publishers can leverage this tool to enhance their ad strategy, drive higher revenue, and navigate the complex ecosystem of digital advertising with greater confidence and clarity. Let’s get into it!
OpenRTB Overview: Understanding the Basics
To get into the OpenRTB overview, it's essential to grasp the basics of real-time bidding in mobile advertising. RTB is a method for buying and selling ad impressions through real-time auctions. App advertisers bid on impressions, and the highest bidder wins the placement to display their ad in a publisher's app. OpenRTB is the protocol that facilitates these RTB transactions in a transparent and standardized way. In the app ecosystem, publishers use supply-side platforms (SSPs) to sell their ad spaces to advertisers, who connect through demand-side platforms (DSPs) to buy these spaces.
SSPs and DSPs communicate using OpenRTB, exchanging information in JSON about the ad impressions they are buying or selling. This information is crucial for buyers to make informed targeting and pricing decisions and to place their bids on the ad space.
This information includes publisher details, distribution channel and its content, ad format and size, geolocation, device type and its user, regulatory constraints regarding data privacy, and the type of auction.
Here's how open real-time bidding works in four core steps:
The SSP or exchange sends a bid request, impression object, and sometimes additional data on impression context.
The DSP decides whether to bid on the impression.
The DSP replies with either a bid response or a no-bid response.
The ad exchange informs the bidders whether they have won or lost the auction.
Since the industry-wide adoption of OpenRTB in 2012, we’ve got multiple detailed technical protocols for numerous OpenRTB versions. Most bidders support OpenRTB 2.5, which is considered the standard version.
How OpenRTB Streamlines Programmatic Advertising
OpenRTB (Open Real-Time Bidding) streamlines programmatic advertising by providing a standardized protocol for the automated buying and selling of digital advertising space. Here’s how it accomplishes this:
Standardization: OpenRTB establishes a common language for communication between different platforms involved in programmatic advertising. By defining how bid requests and responses should be formatted, OpenRTB ensures that supply-side platforms, demand-side platforms, and ad exchanges can seamlessly interact.
Real-time auctions: OpenRTB enables real-time auctions where ad impressions are bought and sold in milliseconds. When a user visits a webpage or opens an app, a bid request is sent to multiple DSPs, which respond with their bids almost instantly. The highest bid wins, and the corresponding ad is served to the user.
Transparency: The protocol promotes transparency by including detailed information in bid requests. This information can encompass publisher details, content of the distribution channel (app or website), ad format and size, geolocation, and other specifications.
Efficiency: By automating the ad buying process, OpenRTB reduces the need for manual negotiations and direct deals. This automation not only speeds up transactions but also reduces operational costs for both buyers and sellers.
Targeting and optimization: The rich data included in OpenRTB bid requests allows advertisers to perform precise targeting and bid adjustments. They can target specific audiences based on location, device, user behavior, and other criteria, optimizing their ad spend and improving campaign performance.
Interoperability: OpenRTB’s standardized approach ensures that different platforms and technologies can work together without compatibility issues. This interoperability allows for a more robust and scalable advertising ecosystem, where various players can integrate and collaborate effectively.
Flexibility: The protocol supports a wide range of ad formats (native, banner, audio, video) and devices, accommodating the diverse needs of advertisers and publishers. This flexibility ensures that OpenRTB can be used across various media and advertising strategies.
Evolution and improvement: Since its inception, OpenRTB has continuously evolved, with the IAB Tech Lab releasing updated versions to address new industry needs and challenges. For instance, most bidders now support OpenRTB 2.5, which is considered the standard version. These updates help maintain the relevance and efficiency of the protocol in a rapidly changing digital landscape.
OpenRTB streamlines programmatic advertising by creating a standardized, transparent, and efficient framework for real-time ad transactions. This enhances the ability of advertisers to reach their target audiences and allows publishers to maximize their ad revenue.
Benefits of OpenRTB for Publishers
No OpenRTB overview would be complete without a thorough discussion of its benefits. Here at Pubcircle, we’ve seen numerous publishers extract immense value from RTB.
Enhanced efficiency in buying and selling ad inventory
OpenRTB automates the process of buying and selling ad inventory, significantly reducing the time and effort required for manual negotiations and direct deals. This leads to faster transactions and reduced operational costs. The protocol facilitates real-time bidding, where ad impressions are auctioned in milliseconds. This immediate process ensures that publishers can quickly fill their ad inventory with the highest-paying ads. By standardizing the bid request and response formats, OpenRTB ensures a smooth and efficient workflow between SSPs, DSPs, and ad exchanges, minimizing the risk of errors and compatibility issues.
Greater transparency in the ad transaction process
OpenRTB includes comprehensive information in bid requests, such as publisher details, ad format and size, geolocation, device type, user data, and regulatory constraints. This transparency allows advertisers to make informed bidding decisions. Publishers benefit from understanding how bids are evaluated and selected, providing insight into the value of their inventory and the factors driving demand.
The transparency promoted by OpenRTB fosters trust between publishers and advertisers. Publishers can verify that their inventory is being sold in a fair and open marketplace, and advertisers can see exactly where their ads are being placed.
Access to a larger pool of advertisers and demand
OpenRTB connects publishers to multiple DSPs and ad exchanges, significantly expanding the pool of potential buyers for their ad inventory. This increased demand can lead to higher bid prices and better revenue opportunities. By leveraging OpenRTB, publishers can attract a wide range of advertisers, from small businesses to large corporations, across various industries. This diversity can help mitigate risks associated with reliance on a few major advertisers. The open auction format encouraged by OpenRTB promotes competition among advertisers, which can drive up bid prices and increase the overall revenue for publishers. More competition typically results in higher eCPMs (effective cost per thousand impressions).
Implementing OpenRTB: Best Practices
OpenRTB offers publishers enhanced efficiency in managing their ad inventory, greater transparency in the ad transaction process, and access to a larger pool of advertisers and demand. These benefits collectively help publishers maximize their ad revenue and optimize their advertising strategies.
