Ogilvy Washington and the Center for Social Impact Communication at Georgetown University have released a white paper, Using Social Media Platforms to Amplify Public Health Messaging, developed and created under the 2010 Social Marketing Fellowship
You can access the white paper by clicking here.
Now this was a great white paper.
The white paper has up to date stats on health information seeking by key demographics, background info on social media, with a specific focus on metrics and tracking. I really enjoyed this one. Props to Ogilvy and the Center for Social Impact Communication for an extremely useful document.
