Optimizing Web Performance with Phased Rendering in Adobe Experience Manager

Web speed is critical to maintaining an excellent user experience, search engine rankings, and conversion rates. Phased rendering in Adobe Experience Manager (AEM) is a great way to improve online speed. 

Phased rendering allows quicker page loads by prioritizing vital material first and gradually loading other pieces. This strategy minimizes perceived latency while improving performance, particularly for complicated online applications.

Therefore, this blog looks at the different aspects of optimizing web performance with phased rendering in AEM. Let’s get started!

Understanding Phased Rendering in AEM

Phased rendering is a method that allows some aspects of a webpage to load sequentially rather than all at once. Instead of waiting for the complete page to load before showing information, phased rendering prioritizes above-the-fold items and defers less critical components.

In AEM, phased rendering may be achieved by lazy loading, server-side rendering improvements, and client-side upgrades. Developers can use AEM’s robust architecture to enhance page performance and drastically minimize bounce rates.

Benefits of Phased Rendering

1. Improved Page Load Speed: Emphasizing above-the-fold material helps consumers perceive a speedier experience, which reduces irritation and increases engagement.

2. Enhanced SEO Performance: Search engines like faster-loading pages, which can boost ranks and organic visitors.

3. Optimized Resource Utilization: Efficiently loading resources in stages avoids server overload and optimizes bandwidth utilization.

4. Better User Experience: Users can interact with visible material while other pieces are still loading in the background.

5. Reduced Bounce Rates: Users are less likely to leave a site if the pages load faster.

Key Phases of Rendering in AEM

1. Server-Side Rendering (SSR)

Server-side rendering guarantees that key material, including hero sections and navigation bars, is preloaded before it is delivered to the client. This method considerably improves the first page load time.

2. Client-Side Rendering (CSR)

Following SSR, dynamic components such as interactive forms and animations are rendered on the client side. This strategy reduces server load while increasing website responsiveness.

3. Progressive Hydration

Rather than displaying all JavaScript-heavy elements simultaneously, AEM supports progressive hydration, which loads interactive components sequentially. This strategy enables seamless transitions and avoids performance bottlenecks.

4. Lazy Loading

Lazy loading delays the loading of non-critical resources, such as photos and movies, until they are needed. This reduces the initial load time and conserves bandwidth.

5. Asynchronous Content Loading

Asynchronous loading guarantees that supplementary scripts and widgets are retrieved concurrently without interfering with significant content, decreasing latency, and increasing user experience.

Implementing Phased Rendering in AEM

1. Prioritizing Critical Content

The first step in phased rendering is identifying and prioritizing vital material to be loaded initially. This includes:

• Page headings, navigation menus, and hero images
• Primary call-to-action buttons
• Key text and important media components

AEM enables developers to alter templates and components so that these elements load quickly while secondary information is deferred.

2. Using Lazy Loading for Media Assets

Lazy loading is a popular phased rendering approach that delays loading pictures and videos until required. This decreases the first page load time and enhances performance.

• To implement in AEM, use the loading=”lazy” tag on images in components.
• Use AEM’s built-in image presets to optimize pictures dynamically based on the user’s device.

3. Asynchronous Loading of JavaScript and CSS

Loading JavaScript and CSS files asynchronously ensures that render-blocking resources do not delay content presentation.

AEM best practices include 

• Using the defer or async properties for JavaScript scripts.
• Reduce HTTP requests by minimizing and bundling CSS files.
• Use AEM ClientLibs to handle dependencies efficiently.

4. Server-Side Rendering (SSR) with AEM

AEM includes powerful server-side rendering (SSR) features that pre-render pages before providing them to users.  This guarantees that key material is readily accessible, which improves perceived performance.

Key techniques:

• Use AEM Sling Models to create JSON-based server-side replies.
• Pre-render commonly visited material and cached responses to ensure quicker delivery.

5. Caching Strategies for Optimal Performance

Caching is essential for phased rendering since it stores pre-computed replies and reduces server load.  AEM supports a variety of caching techniques, including:

• Dispatcher Caching: Caches static and dynamic material on the CDN level.
• Browser Caching: Uses Cache-Control headers to direct browsers to save assets locally.
• Edge Caching: This implements edge caching to minimize latency for worldwide users.

6. Progressive Enhancement for User Interactivity

Progressive enhancement guarantees a webpage is usable before all scripts and styles are loaded.  Key strategies include:

• Providing alternative content for browsers that do not support JavaScript.
• The fundamental functionalities are implemented using lightweight HTML and CSS.
• Once all scripts have loaded, the interaction will be enhanced dynamically.

Phased Rendering Techniques for AEM Components

1. Component-Level Rendering Optimization

AEM components should be organized so that phased rendering works efficiently. Techniques for optimization:

• Divide components into smaller, reusable bits that can load independently.
• For a more streamlined visual experience, use skeleton displays rather than spinners.
• Preload crucial CSS and skip non-essential style sheets.

2. Asynchronous Content Loading

Instead of rendering all content synchronously, AEM allows dynamic components to load asynchronously.

Implementation Steps: 

• Use AEM Sling Models Exporter to provide JSON data asynchronously.
• Implement GraphQL queries to get only the required material on demand.
• Use AEM Content Fragments API to send structured data.

3. Optimized Caching Strategies

Proper caching strategies decrease the burden on AEM servers and speed up content delivery.

Best practices:

• Use browser caching for static files such as CSS and JavaScript.
• Use AEM Dispatcher Caching to save frequently requested pages.
• Use service workers for offline content caching.
