Digital marketing is a term that has been around for quite a while but hasn’t been very well defined, encompassing things like banner advertising, search engine optimization (SEO) and pay per click. Yet, this is too narrow of a definition. What about email, RSS, voice broadcast, fax broadcast, blogging, podcasting, video streams, wireless text messaging, and instant messaging? You get the idea? To clearly define what digital marketing is let’s talk about what it is not. For starters, it does not include more traditional forms of marketing such as radio, TV, billboard and print because they do not offer instant feedback and report. Of course, some people may respond to a call to action from an advertisement in one of these mediums but there is no way to know the exact number of people who saw or heard it. Such data is collected (and still then are only educated guesses) long after the initial ad impression is made. Yes, convergence has made television at bit more interactive, with devices such as TiVo able to record viewer statistics like those for Web sites, but there is still a long way to go. With digital marketing, however, we’re already there.
