When using Amazon Advertising tag (AAt), you must install event code on each page of your website where the user action takes place or use a tag manager to ensure AAt is placed on each page.

This statement is true. For the Amazon Advertising tag (AAt) to effectively track user actions, such as page views, purchases, or sign-ups, the event code must be present on the specific web page where that action occurs. If you're not manually placing the code on each relevant page, a tag manager (like Google Tag Manager) is essential. A tag manager allows you to deploy and manage all your website tags, including AAt, from a single interface, ensuring the tag fires correctly on designated pages without direct code modification on every page. Without proper placement, AAt cannot collect the necessary data for campaign optimization and reporting.
