From your Dashboard, click Manage > User Tracking.
This will pull up a page with a javascript tag that looks like this:
Paste the code just above the </body> tag on your website.
The tracking tag must be installed on every page of your website.
If you're looking to setup dynamic retargeting, make sure to follow our dynamic retargeting overview.

If you're already using Google Analytics or some other analytics product, you probably have some code snippets down there already. It doesn't matter if you put the Site Tracking Tag right before or right after those other snippets, so long as it before the closing </body> tag.
Once the tag is installed, it will take our system 6-8 hours to update and start displaying your audience data, so don't worry if you don't see any activity right away!
