"viral marketing"
Marketing phenomenon that facilitates and encourages people to pass along a marketing message.
The term "viral advertising" refers to the idea that people will pass on and share interesting and entertaining content; this is often sponsored by a brand, which is looking to build awareness of a product or service. These viral commercials often take the form of funny video clips, or interactive Flash games, images, and even text.
Types of viral marketing and viral advertising.
Types of viral campaigns
Pass-along:
A message which encourages the user to send the message to others. The crudest form of this is chain letters where a message at the bottom of the e-mail prompts the reader to forward the message. More effective are short, funny clips of video which people spontaneously forward. Many of these, such as the Cog (television commercial) from Honda began life as TV commercials and have since circulated on the web by word of mouth. The number of people reached in this way is often much greater than the number who viewed the original ad.
Incentivised viral:
A reward is offered for either passing a message along or providing someone else's address. This can dramatically increase referrals. However, this is most effective when the offer requires another person to take action. Most online contests offer more chances of winning for each referral given; but when the referral must also participate in order for the first person to obtain that extra chance of winning, the chance that the referral participates is much greater.
Undercover:
A viral message presented as a cool or unusual page, activity, or piece of news, without obvious incitements to link or pass along. In Undercover Marketing, it is not immediately apparent that anything is being marketed.
User-managed database:
Users create and manage their own lists of contacts using a database provided by an online service provider. By inviting other members to participate in their community, users create a viral, self-propagating chain of contacts that naturally grows and encourages others to sign up as well.
