Understanding effective Facebook content management for Pages is neatly illustrated in the below infographic. Many of the tips are covered in my 1-Minute Marketing Tips for Facebook playlist on YouTube but this handy graphic from Wishpond sums up some of the key points, which include: 

1. Post effective content to Facebook Pages: Max 3 lines of text (100-250 characters), posted 5x per week at optimal hours for your fans, likely during morning and evening commute and post-dinner web browsing times. 
2. Be relevant and compelling: Post unique content to Facebook vs. sharing the same info across multiple social media profiles simultaneously. Reward Facebook fans with special offers, exclusive content and early access to info. 
3. Make a visual impact: Mix in images with your updates so not every post is only text. According to Facebook's stats, posts with photos or videos have 180% more engagement than the average post.
