#16: Do you use urgency triggers? (relevant for stores with discounts, special offers, next day shipping)
If you give your shoppers time to think, they can delay making purchases. Sometimes the delay will be short, sometimes it will be long so they even forget about the product and the offer altogether.
A very effective way of persuading users to make a purchase right now is by creating a sense of urgency. If you have any discounts or special offers in your store, you can always make them time limited and notify users about that. That way you will add sense of urgency.
