Many shoppers change their habits in accordance with what e-commerce discount codes are available. Perfect Search worked with this department store to discover if promo codes or auto-applied discount codes were more effective at improving the site’s e-commerce performance.

Our strategy

For two days, Perfect Search ran an auto-applied discount code for 50% off all qualifying products. This promotion was displayed through sitelink ad extensions, remarketing banners, and shown through automatic price decreases for all qualifying products on the website.

Then, another two-day test ran for a 50% off promo code. This promotion was shown through sitelink ad extensions, remarketing banners, and hero banners on the e-commerce website. However, products showed their full price until the 50% promo code was applied during checkout. 

We wanted to see if the kind of discount code led to a difference in website traffic, conversions, and average order volume (AOV).

What this means for your business

All promo codes are not created equal. Every element of your site should be tested, even promotional offers. This case study exemplifies how a certain type of discount led to more purchases and a higher average order value.
