Page Depth targeting lets you to target based on the number of pages that a user has visited in their session before they see a campaign. Using this option, clients can engage customers based on how far they have ventured into the website.
Each page a user visits will be calculated as a new page view in that session, even if that user has visited it before, or reload the page.
Using this target, you can set the number of pages visited to be greater, less than, equal to or between certain numbers. If a user ends their session or closes the website, this counter will be reset.
