We used to have a 1/4 page years ago, and then we dropped it. since I had ATT for a service provider, we did have a line listing in the yellow Pages. last year we dropped ATT and went with the cable co. for our phone, so now we are not even listed. Heck, most people don't even use the phone books anymore anyway. I never realized we were not in the phone book until a few months ago, but then again, we have all the work we can handle anyway.
SO, we have no listing in the book, we have no web site, only 1 of our trucks has a small logo on it with no phone number, our trailer has no logo or phone number, I don't advertise in any other medium, and I make it hard for people to find me. We are still about 3 months out! HMM... I wonder if that yellow pages thing is a racket?
But then, I'm a tiny company and don't need to high cash flow to keep going. and as for your question, I'd rather get the people that like the feeling of working with a small company instead of a large one.
I never had the largest add in the book, but when I dropped my ad altogether, the only people that quit calling was the window shoppers. so out of the 1-2% of jobs I got from them, my quality high profit customers more than made up for it . Now the only calls I get are froom the YP trying to get my business back.
