Viral marketing is one of my favourites and I'm going to give you a golden nugget of information here. If you have a look at some of the videos on YouTube you will see that there is a, number of views, counter at the bottom right just under the screen of the video and a number of days, weeks, months or years that the video has been running on the left side. Some of the most viewed content on YouTube is funny content, for instance there was a well known video called "Charlie bit me" a few years go about two young brothers one baby brother biting the other one on the finger which was very funny and it had over 62 million views in a very short period of time. Now imagine you had a video with content like that with your web address printed at the bottom as a subtitle, out of 62 million viewers how many would have a look at your website? (Even if it was only 1% that is still 620,000 potential customers). People also take these videos and embed them into their blogs and pass them around face book and other social networking sites this is what you call going viral. The traffic that this generates is of course untargeted but it is traffic none the less and if you manage to create something that does go viral then you could potentially get lots of it. One of the easiest ways of finding content for this type of marketing is to simply record a highly viewed programme off the television, I have had great results with programmes like Britain's' Got Talent and X Factor, remember Paul Potts when he sang for the first time this video had over 10 million views in a week on YouTube it now has over 40 million. Imagine the potential!
