Content marketing is in the SEO field just a term often mentioned (here, here, here, here, here ...). Really agree, the SEOs are not, however, what exactly is behind it.
Content marketing is not a new concept - either in SEO or in other online and offline marketing channels. Topical and explosive the issue is, however, better to have grown through the efforts of Google, and quality for the particular search problem really useful content.
Definition of Content Marketing
There are many statements about what is actually content marketing. For example;
"Content marketing is the art of coming with existing or potential clients with high-quality online content in touch without the equal right to purchase products or services call."
"Content marketing means to attract prospective customers with informative, useful content." Especially in the context of search engine optimization the content has importance.
Where content marketing is about set up under the link Buildings, or to generate attention as linkbait. Consequently the content marketing and link building are not so very different. Goal of content marketing in my opinion is not to generate customers directly or bind, but similar to PR / public relations just to offer primarily the people useful content.
A link to this content and / or a potential sale is strictly downstream here. Content marketing is to be a supportive and favorable to other channels, not directly! The creation of unique and engaging content for marketing purpose helps business in getting high exposure.
The sharing of content on social media platform also helps in marketing.
