My company has a partner relationship with Shopify so I can't go into too much detail but. My rules of thumb:

1) The value of the app to merchants in the app store is taken into account. They look at whether the app fits into the ecosystem and adds value for merchants.

2) Your monetization strategy should involve revenue share with Shopify from the get-go, in a way that scales with the success of your app.

3) The user should not leave Shopify for account registration or authentication.

4) As much functionality should be embedded in Shopify as possible.

5) Do not ever attempt to build something that side steps Shopify's checkout or order data in any way. Shopify payments and transaction fees is how they make money.
