Recently I received a wonderful item to promote for someone, and a beautiful business card, except for one little thing...there was a letter missing from the website url. It wasn't hard to figure out how the word with the letter missing should be spelled, but still, this gives a slight negative impression. There are worse things that one can do to give a negative impression...but even a small thing like this can distract people from the main purpose of your card. With many discount business cards being offered on the internet, places that you visit and choose your card, then do your own layout and typing, it is easy to overlook small things that can make a big difference in how your work and abilities are viewed.
Another thing to think about...a couple of months ago I was at a birthday celebration for a friend...one of the men at the party was unemployed and attending a program that helps the unemployed with opportunities to network. This is a great time to give and receive business cards. He brought one of the cards out for us to look at...it was pretty, with flowers, a verse, and other personal niceties, but lacked a professional appearance. Depending upon what type of work you are looking for, you will want your card to be clear, concise, and professional.
If you have any other tips, please share in a comment, or if you want to send along a scan of your business card, I would be happy to post it here...free.
