In the retail sector, test marketing is a strategic approach where a product or service is introduced to a limited market to assess its viability and gather insights before a full-scale launch. Retailers use this method to evaluate consumer responses, measure demand, and identify potential issues. Test marketing involves monitoring sales, collecting feedback, and analyzing consumer behavior to refine marketing strategies and optimize the product or service offering. This iterative process allows retailers to mitigate risks, make informed decisions, and increase the chances of success when rolling out the product or service on a broader scale.
