Best practice for orchestrating personalized content across AEP CDP, AEM Content Fragments, Adobe Target, and Adobe Journey Optimizer

Hi Adobe Community,

We are designing a personalization architecture for our company’s website and mobile app using Adobe Experience Cloud, and I would appreciate hearing how others have implemented a similar solution.

Our current ecosystem includes:

• Adobe Experience Platform (Real-Time CDP)
• Adobe Experience Manager (Content Fragments / Experience Fragments)
• Adobe Target
• Adobe Journey Optimizer (AJO)

Our objective is to build a scalable content matrix that supports omnichannel personalization across website, mobile app, email, and push notifications.

Our current thinking is:

• AEM serves as the central content repository where reusable Content Fragments/Experience Fragments are managed.
• Customer profiles, audiences, and behavioral data are managed in Real-Time CDP.
• Adobe Target delivers personalized website and app experiences.
• AJO orchestrates personalized customer journeys across email, push, SMS, and in-app messaging.

However, we still have several architectural questions:

1. How should the content matrix be managed in AEM? What kind of data in CDP should we use to create content matrix? 
2. Where is the best place to manage personalization rules? For ex: Adobe Target, AJO, Real-Time CDP audiences or a combination of all them?
3. How do you manage creating hundreds or thousands of content variants?
4. How do you ensure consistent messaging across channels?
   For example:
   • Website personalization
   • Mobile app
   • Email
   • Push notifications
5. What is the recommended workflow for content authors?
6. Did you work with an Adobe Experience Cloud consulting partner for your implementation? If so, could you share which partner you chose and how they contributed to the project?
