The Add-On Audition

The product you offer matters more than anything else on the post-purchase page. Shoppers have already bought what they came for, so the offer has to read as an add-on rather than a second decision. Low-cost accessories, consumables, and companion items tend to clear that bar. A second full-price hero product usually doesn't.

Run three or four candidates against each other and let profit per visitor pick the winner.

What this test design might look like:

	Control	Variant A	Variant B	Variant C
Offer	Shopify recommendations	Accessory under $25	Consumable refill	Two small items together

Turn on Exclude products in order so you're not offering someone the item they just bought, and Exclude out of stock items so a winning variant doesn't quietly stop rendering when inventory runs out. Both live in General Settings.
