What is the difference between a visitor and a prospect?

The difference between a visitor and a prospect is that a visitor is an anonymous person who visits

your website, while a prospect is a known person who has an identified email address. A visitor

becomes a prospect when they fill out a Marketing Cloud Account Engagement form, click on a

tracked link in an email, or are manually imported into Marketing Cloud Account Engagement. A

prospect does not necessarily have an opportunity, a Marketing Cloud Account Engagement form

submission, or an assigned user, but a visitor does not have any of these either. Reference Visitors

and Prospects
