Still need to add the UET tag tracking code to your website and not sure where it is? It is easy to find in Microsoft Advertising.
From the top menu, select Tools > UET tag.
If you're using the new Microsoft Advertising navigation, from the navigation menu on the left, hover over Conversions and select UET tag.
If you have associated the UET tag with conversion goals, you can also select View tag in the Tag ID column on the Conversion goals page.
