Booster Coupon Key Summary

* Based on the data of the Blackbird exhibition held in May, 26

1. Why Booster Coupons Exclusive Accounts Are Increasing Payment Conversion Rate

If you are a maker who is new to funding and does not have enough advertising expenses, it is a big concern how to inform your supporters even if you make a good product.  Wadiz has set up a place for these makers where they are exposed to the top of the exhibition page without buying separate advertisements. This is the account dedicated to booster coupons. According to an analysis of the Blackbird exhibition data conducted by Wadiz in May 26, the project exposed to this account had a 2.3 times higher conversion rate compared to the average page of the exhibition.

Why is there such a difference?

It's because the supporters who go through this account are not just looking around, they've already seen the benefits and moved. And the well-designed booster coupon is the ticket to enter this place.

2. Effective Discount Rate, Key Criteria for Booster Coupon Design

Many makers think about the discount amount first, "whether to cut 3,000 won or 10,000 won." However, looking at the data, the factor that determined the supporter's purchase was not the discount amount, but the effective discount rate.

• Effective discount rate = Discount amount ÷ Minimum settlement amount
• Even if it's a 10,000 won discount, if the minimum payment is 200,000 won, the discount rate is around 5%. On the contrary, even if it is a 5,000 won discount, if the minimum payment is 60,000 won, the perceived discount rate is around 8%. Even if it looks like the same coupon, the benefits that supporters feel are completely different.

The part you often miss is when you hang a large amount (10,000 won) and set the minimum payment higher than 200,000 won. It's issued a lot, but it's used the least. The discount rate is low, so the supporters don't feel the reason to use it.  The booster coupon issued in consideration of the effective discount rate was 3.5 times higher than the coupon that did not.

✅ Ready-to-use recommendation combination

Discounts of 3,000 to 9,000 won + minimum payment of 50,000 to 100,000 won + discount rate of 8% or more

Tip) Set the minimum payment amount near the reward customer price (average payment amount). If it's much higher than the customer price, it becomes an "unused coupon."

3. How to use booster coupons by funding stage

If you've issued coupons for the high-efficiency section, what's important now is how you operate according to the flow of the project. 
Efficient use of booster coupons at each stage of funding can increase the conversion rate of payments and the probability of successful funding together.

Before the Open (scheduled to open) — With the benefit of collecting notification applications

The payment at the beginning of the opening comes first from the notification applicant. In fact, the sales made by notification applicants account for 56% of the total sales. 
Make a booster coupon as the reason for notification application, such as "If you apply for notification, we will give you a coupon that you can use right after opening." If you combine it with the first-come, first-served and limited quantity, the effect is stronger.

Immediately after opening (first three days) — Open Run Coupons fired in the early stages

72 hours immediately after the opening determines the initial ranking. Advance the payment time with a coupon for "72 hours after opening."
When combined with participating events such as supportive comments, not only payments but also comments and support signature indicators go up, which is advantageous for exposure.

Before closing (7-2 days) — Coupons to push the final decision

This is when supporters who already know the project are thinking about buying it or not. One coupon for the deadline will pull up the delayed payment.  The key is to clearly show the rest of the period like "D-3, 72 hours limited." Well-designed booster coupons boost your payment conversion on their own and at the same time create an opportunity to be exposed to your pre-show booster account.  Please refer to the guide and design it according to the project you are working on.
