A piece of content is many pieces of content.
A webinar is a webinar, and it is also a blog post, short clips for social media, multiple banners for different campaigns, an infographic with insightful numbers.
A case study is a case study, and it is also multiple blurbs for your landing pages, a script for a video explainer on the impact of your product, copy for campaigns, testimonials for your social posts.
A video tutorial is a video tutorial, and it is also a blog post good for people trying to figure out what your product can do, screenshots for a knowledge base article, on-boarding content for new employees.
The reason why you need a content engine is not to produce more content, but to make the most out of the content you already have or are about to have.
That’s what makes the difference.
