State Department officials spent $630,000 to get more Facebook “likes,” prompting employees to complain to a government watchdog that the bureau was “buying fans” in social media, the agency’s inspector general says.

The department’s Bureau of International Information Programs spent the money to increase its “likes” count between 2011 and March 2013.

“Many in the bureau criticize the advertising campaigns as ‘buying fans’ who may have once clicked on an ad or ‘liked’ a photo but have no real interest in the topic and have never engaged further,” the inspector general reported. …

Despite the surge in likes, the IG said the effort failed to reach the bureau’s target audience, which is largely older and more influential than the people liking its pages. Only about 2 percent of fans actually engage with the pages by liking, sharing or commenting.
