People use search engines to find quality, authoritative content that meets some need. They need to seek help with a product or service. They need to buy products and services that solve a certain problem. They need to consume media and entertainment. Common examples of this kind of digital marketing content include blog posts, infographics, video, e-books, white papers, social media posts, and case studies, though there are many others.
Creating content and orchestrating its dissemination for easy discovery by your target audience is sometimes referred to as content marketing. Again, content marketers and digital marketing agencies will apply and consider SEO principles in their content strategy to ensure that content ranks highly on search engines and reaches the right audiences.
