What are responses?
In Voyado Product Discovery, a response is how many times a recommendation has been requested. The engine does not know if the recommendations were actually displayed on the site.
If the engine returns an empty recommendation list, it will not count as a response (Note: this behavior changed as of April 2025, older data still count empty lists).
We only count responses for non-bounce sessions.
How does purchase tracing work?
For each purchased product, we trace back to the first time it was clicked during the current session.
- If the product is clicked in multiple recommendation lists, only the first list where it was clicked will receive credit.
- If the product is clicked first in a search result and then in a recommendation list, the recommendation will not receive credit for the purchase.
What is the Add-to-cart rate?
Add-to-cart rate = (Product added to cart from recommendations / Clicks on recommendations) × 100
What is the conversion rate?
Conversion rate = (Purchases from recommendations / Clicks on recommendations) × 100
Why aren't all algorithms shown?
If an algorithm has no recorded user interaction (i.e. clicks, add-to-carts, or purchases), it will not be shown in the table.
