Dear Business Owner,
If you are going to include a web page URL in your paid advertisement or yellow-page listing, might I offer the following recommendations:
1. Have a website that displays when I enter your URL as listed in your ad.
2. If you offer a "Contact Us" link, be sure there is an "Us" to be contacted.
3. If a prospective customers contacts "Us" via the provided link, reply to the prospective customer.
If you, however, are not really advertising your business in the hopes of gaining more customers or if your business is just a front for your illegal activities, then, by all means, ignore my suggestions.
