This document introduces inbound marketing. It discusses how inbound marketing pulls potential customers to a business through content like blogging, social media, and SEO rather than interrupting potential customers through outbound tactics like ads. It outlines the 4 steps to successful inbound marketing: create optimized content, promote that content strategically using social media and other channels, convert leads and analyze results to improve efforts. The goal of inbound is to build authority and earn links organically rather than pay for ads or promotions.
