Should I retarget for Black Friday?

As an e-commerce business owner, I'm strategizing my Black Friday marketing approach and wondering whether retargeting campaigns are worth the investment. With increasing ad costs and competition, I need to understand how to effectively re-engage past visitors and customers during this critical sales period. My main concerns are budget allocation, potential return on ad spend, and creating a strategy that doesn't feel intrusive or desperate. I want to maximize my Black Friday revenue without wasting resources on ineffective targeting methods.
