When to Use Content Fragments vs Experience Fragments in AEM?

by @daniel-strmecki

Introduction

In Adobe Experience Manager (AEM), reusability is key to creating scalable and efficient digital experiences. Many teams begin by focusing on components, but components alone can only go so far. They define layout and functionality, but often blend content with design. This makes it difficult to reuse information consistently across multiple channels, websites, regions, or campaigns.

That’s where Content Fragments and Experience Fragments come in. These two tools let us separate content from presentation in complementary ways. When used correctly, they help deliver consistent brand experiences faster, reduce duplication, and make content easier to manage across all digital channels. Understanding when to use each is essential for building flexible authoring workflows and omnichannel experiences. 

Choosing the wrong fragment type for the wrong purpose, however, can increase complexity, slow down authoring, and make long-term maintenance and updates unnecessarily difficult.

Key points

Content Fragments vs Experience Fragments

In AEM, Content Fragments represent reusable, presentation-agnostic pieces of structured content. Each fragment is based on a Content Fragment Model, defining fields such as text, images, and links to images, files, or other content fragments. Because they are not tied to any visual layout, they can be used anywhere: on web pages, in mobile apps, or in any external systems via AEM’s JSON or GraphQL APIs.

Experience Fragments, on the other hand, are reusable groups of components that include both content and layout. They represent complete sections of an experience, such as a hero banner, promotional area, or footer. They can be reused across multiple pages or exported to other Adobe platforms, such as Adobe Target and Adobe Campaign, for personalization and distribution.

Adobe recommends using Content Fragments for structured content that needs to be delivered in many different forms, and Experience Fragments for layout-driven, branded experiences. When used together, they allow organizations to balance flexibility and design consistency, two essential goals in modern digital content management.

When to Use Content Fragments

Content Fragments are best used when we need to manage structured, reusable content that isn’t tied to a specific presentation. They’re ideal for information that needs to appear consistently in multiple contexts, such as contact details, author bios, FAQs, or press releases. They’re suitable for reusable content that may need to look different across various channels.

Because they are channel-neutral, Content Fragments enable true omnichannel publishing. Teams can author content once and deliver it everywhere: websites, apps, kiosks, or basically any device connected to the internet. This separation of content from layout improves governance, streamlines translation workflows, and makes updates far more efficient.

When designing Content Fragment Models, it’s best to think of them like API schemas. They should be stable, typed, and minimal. Each model should capture only the structured data that will remain consistent across channels. Editorial differences, such as long versus short copy or localized variants, can be handled through Content Fragment variations, not separate fragments. We recommend keeping all fragments organized under /content/dam/<site>/content-fragments/... and group them by domain, for example, /articles, /contacts, or /press-releases. We should treat Content Fragments as source content: version them before large edits, and reference them from pages, Experience Fragments, or even other Content Fragments.

When to Use Experience Fragments

Experience Fragments are most effective when we want to reuse content that already includes layout and design. They are perfect for campaign sections, banners, hero areas, or other branded blocks that should look identical across multiple pages or sites.

They help enforce brand consistency, speed up authoring, and reduce duplication, especially in multi-site or multi-market setups. Experience Fragments also integrate seamlessly with personalization tools like Adobe Target, allowing brands to reuse designed experiences while still tailoring content to different audiences. If the goal is to maintain a consistent look and feel while giving authors flexibility to reuse styled components, Experience Fragments are the right tool.

When creating Experience Fragments, mirror your site structure within the Experience Fragments tree, for example, /content/experience-fragments/<site>/uk/en. Avoid deep nesting, as one level is usually enough. Keep variant sets lean by separating them only when necessary, such as by channel, locale, or campaign. Name variants predictably, like “default,” “mobile”, “email”, and so on. To maintain design control, lock down allowed components via policies so authors can’t unintentionally alter the approved layouts. Above all, don’t use Experience Fragments for structured data or situations where the same content needs to appear in different designs; that’s what Content Fragments are for.

When to Use Both

Often, the best solution combines both fragment types. We can embed Content Fragments inside Experience Fragments, gaining the benefits of structured content within a reusable layout.

In these scenarios, it is important to keep the boundaries clear: Content Fragments should remain responsible for the data and textual content, while Experience Fragments should handle layout and styling. Use this combination when structured information (like bios, testimonials, or contact information) needs to appear within reusable design sections such as hero banners, card lists, or teasers.

@daniel-strmecki Thanks so much for sharing this, thoughtful breakdown. The way you’ve compared CFs and XFs with clear “when to use what” guidance is exactly the kind of clarity many teams look for, especially as more orgs move toward API-driven and omnichannel models. Your point about treating Content Fragments like stable schemas and Experience Fragments as reusable design units is a nice one and something I see trip teams up most often when scaling authoring across markets.

I’d love to hear more about your experience working with hybrid setups. In your projects, what’s the most common pitfall you’ve seen when teams try to mix CFs inside XFs, and how do you usually help them avoid over-engineering the model or the layout?

Hi @kautuk_sahni,

thanks! The most common issue I see is with publishing and caching behavior, as XFs follow page publication rules, while CFs follow asset rules. When mixed, teams routinely hit cache inconsistencies such as:
• CF updated, but XF doesn't reflect the change immediately
• XF updated, but doesn’t republish the referenced CF

Over-engineering can happen at any later, we always need to try to keep things as small and simple as possible. For example, create and reference smaller CFs instead of creating a gigantic one.
