We use Dynamic Yield within our product department to run A/B testing for our consumer experiences, and surface targeted on-site merchandising and promotion messaging in coordination with our marketing department.
The primary impact we have seen from using the product has been the ability to remove the traditional engineering workflow for many Product and Marketing needs into a self-service platform. Where we would previously need to make requests for our developers to build out things that may not be kept around long-term, or have them help with difficult implementations and workarounds in other platforms, Dynamic Yield offers an option to utilize pre-built templates or have our engineers help with upfront building of reusable templates. This process is far less costly and reduces the amount of code in our codebase that was being used for one-time marketing messages, testing, and so on.
Dynamic Yield offered the platform most similar to what we were hoping for (a unified A/B testing and personalization/marketing platform that kept everything in one place) at a price point we were looking for.
We would have been more limited in A/B testing with some of the other platforms because of the way many choose to look at testing vs. personalization. In particular we didn't want to be limited by monthly caps for testing our users.
Dynamic Yield also offered integration with BlueKai for DMP segmentation and audience creation, which wasn't not common at the price point we were looking at.
Well-suited for marketers looking to benefit from a unified A/B testing platform with easy personalization, targeting, and promotional messaging functionality, instead of having platforms where the testing and other features are separate.
I wouldn't recommend Dynamic Yield for companies that are lacking a sufficient development team (primarily front-end) supporting the marketers who would be using this tool. Much of the benefit comes from the advanced templating that can be done to automate the creation of tests, which requires strong development skills.
