Inbound marketing is subtle and involves attracting customers through interactive media such as social media, blogs and webinars. The messaging is tailored to helping a specific group of people solve a problem. Since inbound marketing leverages several digital marketing channels, results are measurable. Outbound marketing adopts a hands-on approach in reaching out to customers to increase conversions. Often through non-digital media such as billboards and magazine, outbound marketing is wide-sweeping and seeks to stand out among millions of other ads. The physical nature of this approach makes measuring attribution difficult.
