Simply put, inbound marketing is marketing that’s focused on getting found by customers. It’s the antithesis of the annoying telemarketer that calls you at precisely the worst possible moment. Inbound marketing doesn’t aggressively steal your attention, it earns it by providing you with interesting and useful information. Inbound marketing waits for you to discover it, then it offers something valuable in exchange for a few moments of your time.
