Frequently Asked Questions

How does the AI recommendation engine work?

AOV.ai analyzes your product catalog, historical sales data, and real-time customer behavior to identify which products are most likely to be purchased together. The AI continuously learns and improves its recommendations based on actual conversion data from your store.

Do I need a lot of traffic for the AI to work?

The AI starts working immediately using your product catalog and sales history. However, the recommendations become more accurate over time with more data. Stores with at least a few hundred monthly orders will see the fastest optimization improvements.

What counts as a pageview for pricing?

A pageview is counted each time a customer loads a page where an AOV.ai widget is displayed. This includes product pages with bundle widgets and cart pages with upsell offers. Admin page loads and bot traffic are not counted.

Can customers upload images for gift boxes?

Yes, ZenBox supports custom forms with text input and image uploads, making it ideal for personalized gift box builders.

Do bundle discounts stack with Shopify discounts?

Yes, ZenBox creates layered discounts that are compatible with other Shopify discounts, so they can stack.
