Issue addressed: Mass media campaigns have used a range of traditional media (television, radio and print) to communicate health messages. In the past decade the Internet has added to these traditional methods with Web 2.0, smart phone technology and interactive media. 'Find Thirty every day®', a Western Australia population-wide mass media campaign delivered over 2 years, used a combination of traditional mass media, a website, online resources and banner advertising. The aim of the present study is to describe the use of the Find Thirty every day® website during the campaign media activities of May 2008-June 2010. Methods: Cross-sectional self-reported survey data were collected from a random sample of adults using a computer-assisted telephone interview over the period February-March 2010. Objective online analytical measures of unique visits to the Find Thirty every day® website were collected between June 2008 and June 2010. Results: Monthly visitors to the Find Thirty every day® website increased from 3193 in 2009 to 4374 in 2010. During the last two media waves (October 2009 and February 2010), site visits were 5388 and 5272 per month, respectively. Conclusion: The impact of the Find Thirty every day® website was a positive outcome, considering the minimal online presence. So what? Health communication campaign planners should maximise the potential synergy of traditional mass media and new social media in future campaigns. Accordingly, a multidisciplinary approach that includes communication researchers, experts in information systems and a creative team experienced in online environments will need to be the way forward. © 2013 Australian Health Promotion Association.
