I am working with a company that needs to track the users on the website inorder to recommend certain deals based on what they're browsing.
I'm using the user-id provided by the company to identify each user. The only information that I'll be collecting in the future, are page they're viewing, time spent etc.
I hope it shouldn't because the only information that I''ll be using is their user-ids that are provided by the company itself.
This article is a good resource for leveraging user data from external systems to better serve your audience.
