For the most out for your Facebook page:
Make a unique & amazing post.
Update your Business page as per requirement.
Use video strategy.
Facebook messenger plays a big role in engaging.
Always use the new tools when Facebook is updated.
First of all, try to make your posts unique and attractive. No one will come to your page if you are offering the same content everyone is posting. However, that doesn't mean you need to post something that is not in trend.
"Follow the trends but add something from your side into it."
As @lexiavenge said, you can run Facebook ads to reach more people. Using this technique will get you more loyal traffic because they will be interested in your content; for doing this, choose your target audience precisely.
