WetterOnline is a popular and well-loved name in Germany and worldwide. WetterOnline sets standards for everything from weather radar to professional maps and customer-specific weather data processing through its websites and mobile apps. Thanks to its high accuracy and progressive products, WetterOnline regularly accompanies 35 million users worldwide in their everyday lives. 

Being one of the largest and most reliable global meteorological service providers, WetterOnline is always looking to the future with innovative ideas. One of them is using Relevant Yield’s Prebid Server capabilities to monetise its mobile apps with Prebid Mobile.

WetterOnline has been using Relevant Yield’s HB Analytics & HB Manager bundle since Q1 2023, and their experience has been positive for both. As a large-scale publisher with a high traffic volume in mobile apps, WetterOnline must not miss out on in-app ad revenue without overcomplicating its ad stack.

WetterOnline’s Challenges

Monetising mobile apps with header bidding can sometimes be a headache. Mediation or building things in-house might require publishers to spend a lot of money and human resources. Due to this, many publishers hesitate to use Prebid Mobile, but not WetterOnline.

Like any other app publisher, they started carefully and gradually using Amazon, Google’s OpenBidding, and Criteo SDKs. However, they soon realised that without Prebid, they were missing out on a big chunk of ad revenue in their mobile apps, which have 200M+ installs on iOS and Android. 

Determined to improve their monetisation strategy, WetterOnline’s programmatic team started exploring Relevant Yield for an effective and profitable Prebid Mobile integration. 

The Shift to Prebid Mobile

Together with Relevant Yield’s onboarding team, WetterOnline steadily integrated Prebid for their mobile apps, web, and mobile webs. 

The setup of the Prebid Server and SDK is crucial for successful implementation. Like Prebid.js, Prebid Server requires precise configuration, including ad unit setup, price granularity, and bid timeout values. Critical considerations for SDK setup include:

• Viewability: Correct implementation of Open Measurement signals.
• Creative Types: Most are supported by default, but some require explicit declarations.
• Custom Targeting: Passing custom data dimensions to the ad server and analytics.
• Device-Specific IDs: SSP IDs must be specific to the device type (Android/iOS).

Since WetterOnline works with different bidders, paying close attention to each’s requirements for optimal performance was crucial. That’s why we went through every connected SSP to ensure they were connected to their specific endpoints based on geographical location. Together with WetterOnline, our Customer Success team keeps up-to-date with legacy standards and makes necessary tweaks to deliver outstanding results continuously.

Performance Insights

The integration of Prebid Mobile revealed potential disparities in fill rates between Android and iOS, which is typical. However, the overall incremental growth in the value of each ad unit request demonstrated the substantial benefits of adding competition to the ad inventory.

• Incremental Growth: WetterOnline saw an incremental uplift of over 10%.
• Increased Competition: Putting demand through Prebid increased AdX revenues due to stronger competition.
• Improved Relationships: WetterOnline values the customer-partner relationship and the guidance provided by Relevant Yield.
  
  

Conclusion

WetterOnline’s journey with Prebid Mobile is a prime example of in-app header bidding not having to be complicated and resource-consuming to cultivate high yields. Of course, it is not a set-it-and-forget-it project, as it requires meticulous attention to SSPs and demand requirements. This is why app publishers need a helpful tool and knowledgeable partners.
