They are defined as "audio and video content that appear in direct response to a predefined or user defined criteria leading to one or more calls for action". Searchmercials can appear in search results by search engines or directories with one or more calls for action, in contextual ads, in display ads and always provide a call for action. The difference between a commercial and a searchmercial is that a commercial is intended for branding purposes and brand retention and does not call or provide a call for action, whereas a Searchmercial, on the other hand, is requested by a defined or predefined criteria and leads to a call for action. A searchmercial can be audio or video and is represented in text, image, audio or video or any combination of the same.
