I am looking for a popular and successful social marketing campaign for healthy lifestyles.
Example: the Verb: Its what you do campaign.
A good idea is to go to forums related to your product and look for people wanting the solution you’re selling (i.e. having a problem which your product solves). Offer them a link to your product’s page/website. The key to this is to do it as a consumer and not as a seller.
Remember there are no sales pitches in social marketing.
