You should think about the time when you're going to post. When you have engagement on your fan page, Facebook’s Insights give you quite a bit of data on your posts. If you correspond individual posts with the data on visitor actions, you can analyze which content and time of posting performs best on your page. Click your page’s Insights link, which appears in your admin panel at the top of the page, and then export and download a CSV or Excel file of the last 28 days’ worth of data. Each data point is split into three sets: daily, weekly, and 28 days. You can probably delete most of the long-term data.
