Confusing User Interface: Adzerk's user interface has been described as confusing by several users who express dissatisfaction with its usability. They suggest that a UX overhaul is needed to make it more intuitive and user-friendly.

Limited Integrations with SSPs and DSPs: Users mention that Adzerk has limitations when it comes to server-to-server integrations with Supply-Side Platforms, SSPs, and Demand-Side Platforms, DSPs. These integrations are currently limited to Adzerks only which restricts the options for seamless integration with other platforms.

Challenges Running Responsive Tags: Some users face challenges when trying to run responsive tags like Adsense within AdZerk. This limitation hampers their ability to effectively manage inventory and make accurate sales forecasts as they are unable to fully utilize these popular advertising tools within the platform.

Users commonly recommend the following for Kevel:

  1. Integration for certain features - Users suggest that a deeper integration is required for certain features, making it less ideal for companies without at least one committed developer resource. This recommendation highlights the need for a more seamless implementation process to access all the functionality that Kevel offers.

  2. API setup for bulk-adding campaigns and flights - Users recommend working with Kevel to set up an API, which would allow for ease of bulk-adding campaigns and flights. This feature would enhance efficiency and streamline the process of managing and delivering ads on the platform.

  3. Consider DFP instead of Adzerk - Although Adzerk is described as a robust product with advanced features beyond plug-and-play functionality, some users recommend using DFP (DoubleClick for Publishers) instead of Adzerk. This suggests that DFP may be a preferred option for ad serving, potentially offering additional benefits or advantages over Adzerk.

We used it as an ad server to implement client side header bidding with prebid. We also use it for serving direct deals. It's used pretty widely across the whole organization and has been a great asset for managing various different campaigns. It addresses the problem of organization and delivery of ad campaigns. It allows non-technical employees to manage campaigns and ad creatives. It also allows for a great amount of customizability for more technical employees. If there is a solution that was not currently available, Kevel was quick to address the problem and work towards a solution.
  • More personable team that can address customizations needed to the product.
  • Easy to use interface.
  • Frequent product updates with notifications via email.
  • Well documented API.
  • User interface could be faster to load.
For ad serving, implementing client-side header bidding with prebid was actually easier with Kevel than it is with Google Ad Manager in most cases, particularly for display advertising. I found though that with more complex integrations (like video), there were more solutions and code snippets available with other larger ad servers (Google).

  • Kevel enabled us to get up and running with client side header bidding when our team was still small and the technology was still new. This improved our ability to monetize our inventory.
Kevel was an easier initial implementation for header bidding with prebid. The team worked alongside us to make sure everything was operating as intended. We ultimately switched to Ads Manager to access AdX demand and other features that were not possible with Kevel (for instance, EBDA). There are benefits to both but I appreciated the attention we got from Kevel support when we were first working through the implementation. We are still using Kevel for many things, just not as our primary display advertising ad server.
