They say a business with no sign is a sign of no business, but what about a business with a BAD sign?
Perhaps the company has a name that tells you nothing about what you'll find inside.
Perhaps the font is so small that you can't read it while driving by. There is a new company I have driven by every day for the past two months and I still do not know what it is! Imagine that! How do you get business if people SEE your place of business but don't know WHAT business it is?
So take a walk outside and look at your sign. Can drivers read it easily while passing by? Is the font large enough to be easily read? Is the type of business easily recognized?
And remember what looks good on a business card might not necessarily look good at 40 mph!
