Small businesses can find a return on investment (ROI) in social media, but they have a hard time with Facebook.

A new study from Manta provides insight from more than 1,200 small-business owners regarding their top concerns. Manta then created the following infographic from its findings.

The study revealed that social media involvement is increasing among small businesses. "Nearly 50% of SMBs have increased time spent on social media compared to a year ago," Manta says. "More than one in three small-business owners dedicate between one and three hours each week managing their social media channels, while 10% spend more time."

For small businesses, the acquiring and engaging of new customers is the primary goal of using social media, 36% said. Gaining lead generations and referrals (19%) was second.

Other findings regarding small businesses and social media...

• 18% name Facebook as the hardest social media platform to maintain.

• 39% of businesses say they see a return on investment from social media activities.
