Liking with your personal page on FB

 "Like us with your personal page for it to count"  What exactly does that mean?  "for it to count?"  I'm new to this and just wondered why liking with your business page doesn't count?  Count for what??  Hoping you can help me out : )) Thanks in advance from a newbie! I want to make sure I get this right from the start.  Excited for this new week to begin!!!  What are you going to do differently this week to make sure you reach new clients?
