Why Adobe Introduced the Web SDK: Understanding the Shift from AppMeasurement.js
Historically, Adobe’s tracking ecosystem was built on multiple standalone libraries, each serving a distinct function within the data collection and analytics process. These included:
- AppMeasurement.js for Adobe Analytics – This library was the backbone of Adobe Analytics, responsible for capturing user interactions, tracking page views, and sending event data to generate meaningful insights.
- at.js for Adobe Target – Essential for A/B testing and personalized content delivery, at.js allowed businesses to dynamically tailor user experiences based on behavior, demographics, and other targeting criteria.
- visitor.js for Experience Cloud ID (ECID) – This script ensured a consistent user identity across Adobe Experience Cloud products, helping businesses create a unified view of their customers and their interactions across different touchpoints.
- dil.js for Adobe Audience Manager – Designed to handle audience segmentation and data integration, dil.js facilitated the sharing of user data across various marketing platforms to enable precise targeting and remarketing strategies.
While these libraries worked effectively on their own, managing multiple scripts created several challenges. Websites had to load multiple tracking requests, leading to slower performance and increased page load times. Debugging and maintaining data consistency became more complicated, often requiring additional effort from developers. Moreover, real-time data activation and cross-channel personalization were difficult to achieve due to the fragmented nature of these libraries. Recognizing these challenges, Adobe introduced the Experience Platform Web SDK, a unified tracking solution designed to simplify implementation, enhance performance, and improve data accuracy across all Adobe Experience Cloud services.
This fragmented system introduced several challenges:
- Longer Load Times – Multiple tracking scripts slowed down websites, impacting user experience, SEO, and conversions.
- Complex Debugging & Data Inconsistencies – Managing separate libraries made troubleshooting difficult and led to data discrepancies.
- Increased Network Requests – Each script sent separate tracking requests, straining website performance.
- No Real-Time Data Activation – Batch processing delayed insights, limiting instant personalization.
To solve these problems, Adobe introduced Experience Platform Web SDK, which unifies all tracks into a single library that sends data through Adobe Experience Edge Network.
The Web SDK was designed to address these challenges by:
Unifying Multiple Libraries– Bringing Adobe Analytics, Target, Audience Manager, and Identity services into a single SDK.
Enhancing Website Performance – Minimizing client-side processing to speed up page loads.
Enabling Real-Time Data & Analytics– Supporting instant data streaming for better insights and personalization.
Introducing a Flexible Data Model (XDM)– Standardizing structured data collection for more efficient tracking.
