An advertorial is a form of advertising that is designed to look like editorial content. The word is a blend of “advertisement” and “editorial.”
Advertorials are usually found in newspapers, magazines, blogs, and online media. They are meant to inform and/or entertain while subtly promoting a product, service, or brand.
Therefore, the content masks the true message. The article pretends to be informative and to share an objective position. Still, the goal is to present the product or service in a way that stays “below the radar” of the reader.
