AEM Core Components are Adobe-supported, reusable building blocks for common digital experience patterns such as text, images, navigation, forms, tabs, teasers, and content containers.

AEM Core Components
Use Adobe supported building blocks as the default foundation for consistent, accessible, and maintainable AEM experiences
Start with proven authoring needsUse common experience patterns such as text, images, teasers, navigation, forms, containers, tabs, and fragments without rebuilding standard functionality.
Apply approved configurations through policiesUse proxy components, template policies, and documented configurations to apply project standards without giving authors ungoverned options.
Customize only when a real need remainsExtend or create custom components when an approved configuration cannot satisfy a genuine business or experience requirement.
Protect accessibility and responsive behaviorValidate accessibility, responsive design, author usability, and performance when components are configured or extended for the implementation.
Keep the component library sustainableTrack component versions, extensions, dependencies, release practices, and upgrade impact to maintain a healthy AEM platform over time.
Executive Summary
Core Components provide a mature baseline for building AEM Sites experiences. They help teams avoid rebuilding common functionality, improve consistency, support accessibility, and simplify long-term maintenance compared with maintaining a large library of custom components.
Why Core Components Matter
- They provide proven patterns for common authoring needs.
- They reduce custom development for standard use cases.
- They support consistent authoring behavior across sites.
- They can be extended when requirements require approved customization.
- They help teams align with an upgrade-conscious AEM approach.
Common Core Components
- Text, Title, Image, and Teaser.
- Container, Tabs, Accordion, and Carousel.
- Navigation, Breadcrumb, and Language Navigation.
- Experience Fragment and Content Fragment components.
- Form controls and related authoring patterns.
Core Components vs Custom Components
Core Components should be the default starting point for common needs. Custom components are appropriate when a requirement cannot be met through existing configuration or a carefully governed extension. The decision should consider author experience, accessibility, maintenance, and upgrade impact.
Best Practices
- Start with Core Components before proposing custom development.
- Use proxy components and policies to apply project standards.
- Document approved configurations and authoring rules.
- Validate accessibility and responsive behavior after customization.
- Review component versions during platform upgrade planning.
Common Mistakes
- Forking or copying components without a maintenance plan.
- Over-customizing standard behavior for minor visual differences.
- Ignoring compatibility when upgrading AEM or component versions.
- Giving authors ungoverned configuration options.
Key Takeaways
AEM Core Components provide an efficient, scalable foundation for AEM Sites. Teams gain the most value by adopting them deliberately, governing extensions, and aligning authoring standards with reusable experience patterns.
Frequently Asked Questions
Can Core Components be customized?
Yes. Teams commonly use proxy components and approved extensions, but customization should be assessed carefully so it does not create unnecessary upgrade or maintenance complexity.
