To improve the chances of online video content becoming a viral video marketing effort, marketers need to create video that doesn't replicate broadcast commercials and promote the content through different sources.

A list of the most effective viral online video content, compiled by Advertising Age and Visible Measures, found that most of the content was created by professional video producers.

Interesting content that makes a viewer want to share it with friends is one key component of viral video marketing campaigns, but the campaign doesn't just materialize if the content is posted to the web.

Web video marketing content can be measured by the number of video views, the amount of time viewers watched with the content, and how the video helped to convert viewers to an engagement action.
