Capturing Campaign Click Data via Pixel Calls
Click tracking enables measurement of visitor engagement throughout your campaign, as it records click-based activity for third-party creatives. Similar to impressions collection, an event call is sent to the Audience Manager data collection servers (DCS) for processing. The visitor is then redirected to the intended web address.
Requirements
Click tracking calls require the following parameters:
d_event=click: A key-value pair that identifies an event call as a click event.d_rd=redirect URL: A key-value pair that contains a double-encoded redirect URL. If you’re using an online encoding tool, run the string through the encoder, then encode the result again, in order for the redirect to work.
In addition, the call can contain key-value pairs that can be used for trait qualification or to provide data and metadata for other reports.

Supported Macros
Click events support the macros listed in the following table. A macro is a small unit of self contained code that activates when the ad tag loads for campaign and user tracking. The macros will be passed along with the destination URL, as long as they are marked with the following format: %macro%. Some keys do not have macros and accept a hard coded ID value instead. Keys that accept hard coded values are required if you want to analyze data in the Audience Optimization Reports.
