Look at how Target is using satellite maps to help customers find their stores. They're painting a 250 logo on their roof!

@Daniel I agree that it tells you what the place does, but the name is non-sequitur. It's not really "just" if it's "plus". "Nails Plus" would be a more sensible name, and you could make it larger in the allotted space on the pylon sign -- then people could see the name from further away.

Example of a poorly named business near me: Just Nails Plus

Always run your company name by a professional, especially if you are new to the culture where your business will be, or writing is not one of your strengths.

For example: I love Thai food, but trying to spell, pronounce and even remember the name of this one restaurant consistently eluded me when trying to find their phone number for takeout orders. Finally, I got their website URL and bookmarked it: http://www.phobenthanh.com/ I like how the name is authentic, but if your customers can't find you in the phone book then you've got a problem.

Also, make sure your name makes sense! I know of these two business that have similar names: "Just Transmissions and More" and "Just Nails Plus".

This resonates so perfectly, whether the client is a mom and pop operation or a fortune 500 company. Thank you, I'll surely think of this post every time I talk to my clients.
