You can use a specific calendar for spreading link posts across FB. Add '#fbpages' (or change the hashtag below) to each event's TITLE that you want to go to your Facebook Page. In the DESCRIPTION field of the event, put the message you'd like posted on your page. In the EVENT URL add the link you'd like to be posted to your timeline and it will appear as a thumbnail. With a troop of similar Applets, Google Calendar can be your HQ for scheduling posts to Twitter, Tumblr, and Facebook!
