How It Works
A customer journey usually begins when someone discovers a business through marketing, referrals, search engines, advertising, or other channels. After learning about the business, they may become a lead, evaluate available products or services, and eventually make a purchase. Once someone becomes a customer, businesses often continue communicating through customer support, email marketing, loyalty programs, and ongoing relationship management to encourage future business.
