How would you use custom redirects in a paid social campaign?

Custom redirects give you a trackable Account Engagement URL that forwards to any destination, so clicks from a channel you do not control still register as prospect activity and can fire completion actions.

In practice I would create a distinct redirect per creative or placement, rather than one per campaign, so performance can be compared. Each one can add the prospect to a campaign-specific list, adjust score, and apply a tag on click.

The honest limitation: a click only attaches to a prospect if the person is already cookied. A genuinely cold click from social produces an anonymous visitor, and the activity is attributed retroactively only once that person converts. So I would not present redirect click counts as prospect-level engagement for a top-of-funnel acquisition campaign — I would use them for retargeting known prospects and for measuring relative creative performance.
