External Link Tracker Plugin

Track and report on users clicking on external links

Introduction

The goal of this plugin is to track users clicking on external links, and to report on external link tracking statistics. Links are obfuscated and identified only by link IDs, e.g. users can't see the destination link in view mode and edit mode.

An external link is written as %EXLINK{ID}%, with ID representing the link identifier. For example, %EXLINK{TWiki}% renders as TWiki.orgExternal site.

The external links with IDs are defined in a table in ExternalLinkTrackerDefinition. Example - for illustration only:

ID Name URL Comment
TWiki TWiki.org http://twiki.org/  

External link statistics

External Link Tracker Statistics

The ExternalLinkTrackerStatistics topic shows external link tracking statistics. The statistics are typically restricted to members of the ExternalLinkAdminGroup.

Syntax Rules

%EXLINK{ID}% - the ID identifies the external link.

Examples

  • %EXLINK{Google}% expands to: %EXLINK{Google}%
  • %EXLINK{TWiki}% expands to: %EXLINK{TWiki}%
