How do you measure the return on a pack-shot session?

You look at whether the wholesaler orders the reference whose label can now be read, not whether the photo is liked. If the listing still shows the old pack, this session has not entered the sale. Compare orders for that reference before and after the front changes on the listing. In Madrid the ad is changed and the wholesaler listing still shows the previous jar. Carlota notes the reference with the new listing and that week's orders.
