[header] How to get likes on facebook [title] Post on facebook often. [step] You don't have to treat facebook like your personal diary-even just posting once per day is enough to keep your timeline filled with content. When posting, try to come up with unique, engaging content that makes your friends laugh (or cry, as the case may be). 
[substeps] Try to post during times at which you know that your friends are active. You can see who's currently using facebook on desktop by looking for green dots next to people's names in the right-hand sidebar.
