If your Facebook account is not making a great showing on being alive and active or proving yourself as an expert/authority for what you want to be found for. The best way to do this is to create content on the account. Some simple ideas for this are:
If you post regularly on your account, it shows Facebook that you are ‘alive and active’…so they can trust you to be ‘real’.
If you post expert content, it shows Facebook that they can trust you as an expert/authority.
If you show yourself and your brand, that helps build familiarity with an audience, which also shows Facebook that you are ‘real’ and not only trying to use Facebook to market. This builds trust.
If you can get on a regular schedule (ie. Monday/Wednesday/Friday or Tuesday/Thursday – whatever fits you) of posting, that consistency will really help your bottom line.
