Viral marketing involves spreading a message widely through social sharing rather than traditional advertising. It works by creating content that is funny, wow-inducing, or emotional so that people want to share it. The message and delivery must not be about self-promotion but should focus on the reader. Examples include live videos, flash videos, and engaging content on Facebook and Myspace. Landing pages should focus on the reader and inspire them to share the message with others. Content creators must be prepared for success by having sufficient server capacity, tools to gather subscriber information, resources for responding to speaking requests, and products to offer.
