There are a few things you can do to find out who likes your Facebook business page.

  1. Check the comments on your page. If there are any negative comments, it could be indicative that people do not like your business or are not familiar with it.
  2. Check the shares and likes of your page on other social media platforms. If you have a lot of shares and likes on other platforms, it could be indicative that people are interested in what you have to say and how you are doing.
