Viral marketing on the web involves spreading a commercial message by using the readers of this message to relay it to their immediate circle (friends, colleagues, ...). The term " buzz marketing " is also used. These are typically links saying “ send this page to a friend ”.
As with
prospective e-mails, viral marketing for commercial products is subject to strict rules (privacy law). Viral marketing can constitute a very useful and high-performance relay for on-line campaigns, new products launches or in the context of
social networks.
