OpenRTB 3.0 is the largest overhaul of the OpenRTB protocol since its inception in 2010. The purpose of this major update is to meet the market’s demand for security, transparency, authentication, and trust in programmatic advertising.
On July 24, The IAB Technology Laboratory released for public comment the tech specifications for OpenRTB 3.0, built upon the framework released last September, as the second part of a two-phase introduction to the ecosystem to promote healthy growth digital advertising programmatic marketplace. New specifications designed to support OpenRTB 3.0 are also being made available for public comment, including: ads.cert, AdCOM, and the Ad Management API.
The specifications will have a 60-day public comment period, running through September 24, 2018. Beta testing by the IAB Tech Lab OpenRTB Working Group will be ongoing. Industry members are encouraged to actively participate throughout the beta period, and to get involved with the OpenRTB Working Group. The group will evaluate and incorporate the feedback received, as well as real world insights from beta testing, to produce final specs that will be ready for full industry adoption by the end of the year.
Please reach out to [email protected] with feedback or questions.

SUPPORTING OPENMEDIA SPECS: ADCOM 1.0 BETA, AD MANAGEMENT API 1.0 BETA
Note: The new structure of the OpenRTB 3.0 Beta specification requires use of both OpenRTB (transactional specification) AND AdCOM (specification describing objects to be transacted). This layered specification approach is referred to as “OpenMedia.” Previous 2.X versions of OpenRTB were standalone specifications.

Real-time Bidding (RTB) is a way of transacting media that allows an individual ad impression to be put up for bid in real-time. This is done through a programmatic on-the-spot auction, which is similar to how financial markets operate. RTB allows for Addressable Advertising; the ability to serve ads to consumers directly based on their demographic, psychographic, or behavioral attributes.
The Real-Time Bidding (RTB) Project, formerly known as the OpenRTB Consortium, assembled technology leaders from both the Supply and Demand sides in November 2010 to develop a new API specification for companies interested in an open protocol for the automated trading of digital media across a broader range of platforms, devices, and advertising solutions. At the time Programmatic had only accounted for 4% of the display advertising market. By 2017, RTB is expected to account for 29% of the digital mix (source: eMarketer March 2013). This group continues to create open industry standards that ensure all parties, buy and sell side alike, can transact RTB at scale and build future industry innovation.

This spec describes the outer native object, which includes the ad unit (the 6 types of native ads defined by the IAB Native Advertising Playbook) and the layout.
