Content is what you share on the internet in order to connect with your customers or fans. Your audience is not only interested in words or pics but in an audio file (podcast), a video or a live as well. Content creates trust from your discussion partner as he understands you care for him.
Inbound or content marketing means communicating with your prospects or customers to recruit or retain them. You seek to initiate a conversation with them in order to provide them with what they are expecting. The equation to evaluate the value of content is simple:
Value = Incomes / Costs
Content is the fuel of your inbound strategy. Before, your audience was limited. With the internet it has become unlimited but you need to catch attention.
