This model wasn't possible before so it's difficult to compare apples to apples but the increase in performance (products sold through this channel) is around 10x.
We believe 1.x conversion in this scenario is incredibly good considering there's room to improve AND these are transactions. The performance here is better than most mobile CTRs for banners.
Don't know about your target market but to me 10x increase sounds a whole lot better than 1.x conversion rate.
+ I would have loved to see a video with the checkout process
The 10x is harder to define compared to the typical scenario before Two Tap. The real achievement here is the conversion rate considering mobile + commerce + general traffic.
Feel free to test out the checkout at https://core.twotap.com/demo or with other publishers (maybe Honey, the Chrome extension?)
It works for any product from any retailer we currently support and it doesn't impact Apple's payment system, it's an ecommerce transaction outside of it.
