I think I great way to start thinking is back to the basics. Setting a firm foundation first helps you to nail your launch/relaunch.

-What issue or problem does your business solve?
-Who needs your solution?
-Where are those people/ businesses- where do they go, what information platforms do they interact with, who do they seek advice from?
-How do you get your message specifically to those people?
-Who else is out there claiming to solve the problem - your competition?
-What value can you provide that your competition does not provide, or how do you provide it better or more unique in that space?
-What do your current customers say about you (and your competition / other business in that space?
