Adobe Experience Manager Sites Features

Enterprise Headless CMS

Most headless systems stop at content availability: getting content to more places. Experience Manager Sites goes further: structured content built for both people who read it and the AI agents who parse it. Run headless, headful, or hybrid, Experience Manager Sites provides the governance and context enterprises need to drive outcomes that matter—performance, personalization, and visibility across every surface.

Decoupled content management

Separate content from presentation for both headless and hybrid approaches. Experience Manager Sites gives developers framework freedom while giving marketers a governed system for structured content reuse, localization, and enterprise-scale multisite delivery.

Content models. Organize and structure content for your site or app using existing content model templates or by creating your own.
Content Fragments. Design, create, publish, and reuse content across delivery implementations, whether headless, headful, or hybrid.
Content Fragments editor. Quickly create and edit content fragments across digital properties using a familiar form-based editor with bulk editing capabilities.
Experience Fragments. Group content and layouts to create channel-agnostic, reusable fragments that can be published to any screen, ensuring consistent messaging and design without building multiple creative assets.
Multisite management. Quickly create and manage content variations across multiple sites by propagating source content structure to connected live copies. This allows for inheritance across organizations and global content structures.

Visual editing

Edit and preview content in real time — regardless of the front-end framework or where the content is rendered — with what-you-see-is-what-you-get (WYSIWYG) editing in Universal Editor.

Visual editor. Visually edit images, copy, videos, and more as they contextually appear on the page or within the page structure using nested components.
Agnostic framework. Use any front-end framework (React, Vue, Angular, etc.) while easily authoring pages with intuitive drag-and-drop tools. Experience Manager Sites supports any rendering architecture — server, client, or edge across local or remote domains.
Flexible editing. Edit any aspect of the experience, even those that require additional metadata or the application of different styles, such as columns, carousels, tabs, accordions, and more.
UI customization. Customize the Universal Editor by adding extensions, including features such as experimentation, task management, and AI-generated content variations.

Content delivery

Fast delivery is the baseline. Experience Manager Sites APIs make structured content quick to retrieve and render, so experiences load fast for people and stay readable for AI.

GraphQL. Quickly deliver reusable, structured content to other applications in JSON format.
Content Services. Build pages with reusable templates and components and expose them via Content Services APIs as Representational State Transfer (REST) endpoints, providing each page with its URL.
Persisted queries. Reduce query execution using HTTP caches or the Experience Manager Sites content delivery network. Client applications can request persisted queries with GET requests for fast edge-enabled execution.
Web-optimized image delivery. Deliver images from your digital asset manager in WebP format via GraphQL for faster page load times and a 25% reduction in download size on average.

Experience optimization

Go beyond content management to deliver high-performing experiences.

Built for AI discovery. Deliver semantic HTML server-side, structured content via API, and a governed source of truth, to improve how AI describes, cites, and recommends your brand.
Personalization. Optimize customer experiences by publishing structured content to personalization tools like Adobe Target, Adobe Journey Optimizer, or third-party tools for advanced A/B testing and omnichannel personalization.
Build once, reuse everywhere. Create structured, reusable content once using Content Fragments, and deliver it via GraphQL and APIs to any app or front end. This allows teams to create fast, consistent experiences without channel-specific rebuilds as they grow and scale content.

A composable CMS that doesn’t leave marketers waiting on developers.

Compose experiences from reusable content fragments, blocks, and APIs — with the visual authoring, governance, and performance that pure-play composable and headless tools lack. Get composable flexibility and marketer self-service on one connected platform.

What is a headless CMS?

A headless CMS separates content creation from presentation, storing content as structured data delivered via API to any channel — web, app, kiosk, or AI assistant. Adobe's enterprise headless CMS adds visual authoring, governance, and edge delivery on top.
