2/3 of Facebook business pages are inactive or incomplete

"Pages attract business users to Facebook and lead the social network’s efforts to earn advertising revenues. However, this study of 5.7 million Facebook Pages shows that business users are still struggling to adapt to Facebook as an engagement opportunity. The study updates the findings of a similar research conducted by Recommend.ly in March 2012.
The current study discovered low levels of active Pages, fall in average number of posts and a huge drop in engagement rates since March. Page owners clearly need to do more to make Facebook work for them.
The study also found that the share of visual content on Pages has increased after the introduction of Timeline view for Pages. Also, it is found that Pages selecting specific category names such as ‘Spa’ or ‘Restaurant’ tend to be more focused and get better engagement from fans, compared to Pages choosing generic sounding category names such as ‘Local Business’.
Key Findings
About 2 out 3 Facebook Pages are inactive in some way:
63.9 per cent Pages have no cover photo
70.1 per cent Pages make 0 posts a month
83.4 per cent Pages never participated in conversations
50 per cent Pages have less than 300 fans"
