Visitor Groups Usage Report for Optimizely CMS

This add-on helps Optimizely teams audit how Visitor Groups are used across the site so editors, marketers, and developers can review personalization rules with more confidence. Instead of guessing which groups are still active, you can quickly see where they are used and make better decisions around cleanup, optimization, and content targeting.

Originally, I wanted this to appear alongside Optimizely's built-in reports. In CMS 12, that is no longer possible because the GuiPlugIn attribute was removed, so I built it as a dedicated add-on with its own menu entry.

Why this report matters

Visitor Groups often grow over time and become difficult to track, especially across larger Optimizely solutions. This report gives you clearer visibility into where groups are being used, helping teams review personalization rules before changing or removing them.

• See where Visitor Groups are used across site content.
• Review personalization rules before cleanup or restructuring.
• Support safer maintenance of older Optimizely solutions.
• Give editors and admins better visibility into targeting setup.

Installation

Install the package in your Optimizely CMS project with:

dotnet add package A2Z.VisitorGroupsUsage

How to use it

Typical use cases
