Content is still the King

If you want to know how to increase likes on Facebook, the easiest answer is to create content that is unique, exciting, and fresh. Not only should your content be engaging but make sure that it's shareable too.

Involve the people who already like your page and ask for their help to expose your posts to their own friends. Create engaging Quizzes and news articles as they have high share rates.

Sometimes a simple question about the day would help to achieve the interaction you are looking for.
