Content marketing is a technique used in marketing to create valuable and relevant content for a target audience. It is a long-term marketing strategy that relies on consistent information-sharing to build strong relationships with the audience. 

At the core of content marketing is sharing information-rich content with the audience through storytelling. The idea is to pitch high-quality and engaging content instead of simply selling products or services. Content marketers present the content via various mediums (offline, online, or hybrid mediums) and in multiple formats (blogs, videos, ebooks, etc.).

Nonetheless, content marketing can be more effective when applied in addition to other marketing strategies like traditional marketing campaigns.
