Cold calling is a sales technique where a salesperson makes unsolicited calls to prospective customers with whom they have had no prior contact. The term "cold" refers to the fact that the salesperson is reaching out to individuals who are not expecting their call and may not have any prior knowledge of the product or service being offered. The purpose of cold calling is to generate leads, initiate sales conversations, and ultimately secure appointments or sales. Businesses actively use SEO to expand their customer base, promote new products or services, and reach out to specific target markets.
