SalesForce and Pardot Tracking Code
Each Pardot campaign has a unique tracking code that tracks visitor and prospect activity when added to your web pages.
With Tag Manager, you can set this up in a hassle-free way. Start by selecting the Salesforce & Pardot Tracking Code as an asynchronous tag template
In Pardot, go to Marketing | Campaigns > select the Website Tracking campaign and then Click View Tracking Code. From the code copy piAid and piCid
And paste into PI A ID and PI C ID fields in Tag configuration.
Once you have completed entering the tag information, select the trigger corresponding to the landing page where you would like to fire the tag or create one if it doesn’t exist already and click Save.
