How do I compete for Cyber Monday ad space?

As an e-commerce business owner, I'm struggling to make my Cyber Monday advertising stand out in an increasingly crowded digital marketplace. With massive brands and competitors investing heavily in ad spend, I need strategic approaches to capture consumer attention, optimize my budget, and create compelling ad campaigns that cut through the noise. I want to understand how smaller businesses can effectively compete and maximize their visibility during this critical shopping period without burning through their entire marketing budget.
