Track metrics like:
Social Mentions: Encourage customers to tag your brand with the bag (e.g., #MyBrandTote) and count posts/reaches.
Repeat Purchases: Offer a discount code printed on the bag (e.g., “TOTE10”) to track how many customers return.
Impression Estimates: Multiply the number of bags distributed by the average uses per bag (100–150) to calculate total impressions.
