The automation tool that would best achieve this is to create a page action set to tag prospects as having viewed it and add them to a list. A page action is a feature that allows you to track and act on the behavior of prospects who visit specific pages on your website, such as your pricing page, product page, or thank you page. You can use page actions to perform actions on the prospects who visit the page, such as adding them to a list, assigning them to a user, or changing their field values. You can also use page actions to customize the content or layout of the page based on the prospect's attributes or behaviors2. To create a page action, you need to specify the URL of the page that you want to track, and the actions that you want to execute when a prospect visits the page. For example, you can create a page action that matches the URL of your pricing page, and tags the prospect as having viewed it and adds them to a list of pricing page visitors.
