Explanation: One way a sales rep can convert a visitor to a prospect is by manually associating the visitor with a prospect. A visitor is an anonymous person who visits your website, while a prospect is a known person who has an identified email address. A sales rep can use the [Visitor Activity page] in Marketing Cloud Account Engagement to see the visitors who have interacted with your website, and manually associate them with a prospect if they have an email address. This will convert the visitor to a prospect and allow the sales rep to follow up with them. The other options are not ways to convert a visitor to a prospect. Giving the visitor a phone call, increasing the visitor’s score, or walking the visitor through a demo are ways to engage with a prospect, but they do not identify the visitor’s email address or associate them with a prospect.
