There's no doubt that web searches will increase your exposure. You just have to be very careful in designing your site so that you don't get calls from people on the other side of the country. I made the mistake of not doing this and within one hour, I was receiving calls from customers in South Dakota and Utah.
I'm becoming a firm believer in purchasing Google ad words to direct local people to your site. You can pick and choose what type of exposure you want and if it doesn't work, you can adjust them on the fly. Unlike the Yellow Pages, where your mistakes can last a year or even longer, web-based advertising is by far the safest way to go.
