If you are in advertising, you probably already know that digital ad revenue grew in the last year. According to the Interactive Advertising Bureau (IAB), it grew by 22% in 2016, to reach $75.2 billion. But what you might not know is that the shift to mobile and advertising’s influence on mobile buying trends go hand in hand.
Shift to Mobile
Not only has the amount of time spent online increased in the mobile category, it accounts for 1 trillion mobile minutes in 2016 and has the largest share of online traffic over desktop and tablet (68%). And the ad dollars are trying to keep up. In 2016 alone, more than half of digital ad revenue came from mobile.
OpenRTB Device and Programmatic Growth
This is why more agencies and advertising firms are adopting an Open Real-Time Bidding (RTB) exchange to part of their advertising mix. This year RTB is expected to account for 29% of the digital mix (source: eMarketer March 2013) and programmatic advertising accounts for more than two-thirds of U.S. digital display ads.
Device Detection Enhances the Value of Ads in an Exchange
The more a publisher can tell advertisers about their potential audience, the more valuable a publisher’s ad space becomes. One critical piece of information you can instantly identify is the mobile device. According to Smaato, a leading SSP, clearly identifying a mobile device increases eCPM by more than 29%. And if a publisher, SSP, or DSP can provide other demographic and technographic indicators, like the price paid for the smartphone or its age, then the advertisers will target those viewers, increase their campaign effectiveness while still paying a premium for the right type of audience.
How WURFL Populates the IAB’s OpenRTB Spec
IAB has developed a specification the API for OpenRTB to support for automated trading of digital ads. The API outlines industry standards for objects and parameters that are communicated between buyers of advertising and sellers of publisher inventory. One critical object describes the device used to view the publisher’s web page. To populate this device object effectively, developers need to take the browser’s user agent string and quickly detect the device and several other parameters.
WURFL is the industry’s leading device detection solution, providing 80% of the web’s mobile device analytics, and is used by advertising leaders like Google and Facebook. ScientiaMobile provides several different products to suited to the advertising industry. WURFL can supply more than 500 capabilities describing different attributes of desktops, smartphones, tablets, smart TVs, and game consoles. These device detection capabilities are updated weekly to ensure the highest level of accuracy and speed for OpenRTBs and other programmatic advertisers to correctly optimize ads to the right device, screen, size, and more. To help developers, we have matched WURFL capabilities to the OpenRTB device object’s parameters.
Mapping of OpenRTB Spec Device Object to WURFL
Here is the mapping of WURFL capabilities to the OpenRTB spec device object put out by the IAB:
|ua||User-agent (not a capability, but an input to the WURFL API)|
|devicetype||OpenRTB Device Type ENUM values mapped to WURFL Capabilities
Note: in cases like the Google Nexus 7, the manufacturer, HTC, is available via
|ppi||WURFL reports screen dimensions in mm, so this formula can be used to get PPI:
Step 1: inches =
Step 2: pixels =
Step 3: ppi = sqrt(pixels / inches)
|flashver||No version info, but
|connectiontype||WURFL does not know the current connection type, but
- make: WURFL offers
manufacturer_nameis only set if it is different than
brand_name. For example: “Google Pixel” has
- model: WURFL offers
marketing_nameis only set if it differs from
model_name. For example: “Samsung Galaxy S8+” has
model_name="SM-G955F"(and many others), with
Adding More Capabilities, More Advertising Value
Publishers, DSPs, SSPs and Advertisers can go beyond these parameters and provide even more value. Using WURFL to decode the user-agent string (or resolve the WURFL ID if your trading counterparty provides it), you can add even more detail and increase value. For example, our
is_robot capability will identify bots/crawlers.
is_robot can help limit showing ads to non-human traffic. Below are other ways Advertising firms use WURFL device intelligence.
