Adobe Analytics implementation guide
How Adobe Analytics is implemented in practice: solution design, data layer, tag management, variable mapping, and validation - and where implementations go wrong.
Data layer for Adobe Analytics
What a data layer is in an Adobe Analytics implementation, why it exists, the W3C and event-driven patterns, and the design rules that keep tracking stable.
eVars and props
The difference between eVars and props in Adobe Analytics, expiration and allocation explained, current limits, and what replaces both in Customer Journey Analytics.
Visitor ID and identity stitching
How Adobe identifies visitors - cookies, ECID, and identity maps - and how Customer Journey Analytics stitches device-level data into people. Written plainly.
Web SDK vs AppMeasurement
The difference between Adobe's AEP Web SDK (alloy.js) and legacy AppMeasurement: one library, one beacon, XDM payloads, Edge Network routing - and what migration involves.
Adobe Analytics to CJA field mapping
How Adobe Analytics concepts map to Customer Journey Analytics: report suites to datasets, eVars and props to schema fields and data views, segments to filters, and what has no equivalent.
Data Warehouse and Data Feeds in Adobe Analytics
What Adobe Analytics Data Warehouse and Data Feeds are, how they differ, and what replaces them in Customer Journey Analytics.
Adobe Launch, now Adobe Experience Platform Tags
What Adobe Launch - now Adobe Experience Platform Tags - does, how it relates to DTM and the Web SDK, and what a clean tag management setup looks like.
XDM: the Experience Data Model
What XDM is, how schemas, classes, and field groups work in Adobe Experience Platform, and why schema design decides what Customer Journey Analytics can ever tell you.
Report suites vs data views
How Adobe Analytics report suites map to Customer Journey Analytics connections and data views, and why settings move from collection time to read time.
Segments in Adobe Analytics and Customer Journey Analytics
Adobe renamed CJA filters back to segments in April 2025. What actually transfers in migration, what the Component Migration tool does and misses, and how the containers map.
The AEP Debugger and implementation validation
What the Adobe Experience Platform Debugger shows, how to test an Adobe Analytics or Web SDK implementation, and what validation beyond the browser looks like.
