1. Offer something to induce reciprocity.

One of my favorite persuasion tactics is reciprocity. When we receive something from someone, whether it’s a gift or something as small as a compliment, we feel grateful. Our gratefulness makes us want to reciprocate and give them something in return. This is the power of reciprocity in action. 

We see this implemented in marketing. A brand may offer a special discount on first purchases, which may compel many first-time visitors to make a purchase. Some may offer a discount to people who sign up, compelling many shoppers to register on the site instead of checking out as guests.
