A retailer using a Video action campaign is setting up conversion tracking to measure the results of the campaign.They already capture the important user interactions that create conversions,butthey'reunsure of what other tracking events they can obtain.What should they do to further optimize their campaign?

**Optimize the campaign for"addtocart":**When users add a product to their cart,it indicates a strong intent to purchase.By tracking and optimizing for the"addtocart"event,the retailer can gauge user interest in their products and measure a step that is closer to conversion than just viewing a product.This can provide valuable insights about which products or offers are resonating with viewers,and the retailer can then adjust their campaign or offers based on these insights. Furthermore,optimizing for this event can help in re targeting efforts,where the retailer can reach out to users who added products to the cart but did not make a purchase.
