You can either add scripts at the template level or at the landing page level.
We recommend adding scripts like Google Analytics tracking at the template level, so that you don't have to remember to add it to every page you create.
However, if you need to add a script to a specific landing page, you can do so by following these instructions.
In your landing page, select Landing Page Action and then ‘Edit Page Meta Tags.’
Paste your tracking codes into the Custom HEAD HTML.
