Content marketing involves the creation of valuable, relevant content with the goal of attracting a target audience and ultimately converting that interest into sales.
The key words in this extremely simplified overview are valuable and relevant. Content marketing differs from traditional marketing techniques in that it should attract rather than intrude. In order to get people to come to you, your content has to be useful and engaging enough to hook and retain interest. This can be tricky enough in a monolingual campaign in a language and culture you are familiar with. If you decide to take your content global, however, there are even more things to consider.
