In house or outsourced? That is the question from a recent Social Media Examiner study.

The answer: mostly in house.

According to the 2011 Social Media Marketing Report, 72 percent of marketers who use social media do not outsource it.

However, farming out various aspects of social media marketing has gained traction in the past year. The study found that the percentage of marketers outsourcing social media has doubled, jumping to 28 percent from 14 percent in 2010.

Design/development is most commonly outsourced, with 17 percent of marketers indicating they use an outside agency for the task. Content creation (10 percent) and analytics (10 percent) are the next most common tasks.
