A study shows that customers exhibit an urgency to buy when they feel scarcity. Setting deadlines, including countdowns in campaigns, creating time-limited campaigns, limited stock, showing real-time behaviors of other customers, cart expiration notices are some of the best practices. Display countdown popups for your time-limited offers. Send cart expiration time notice via emails. Don’t forget to write your copy to induce urgency and FOMO as well. Include phrases like “offer expires, hurry, buy today, ends soon, last chance, etc.”
