In this day and age businesses are being scammed almost every minute from scammers posing anywhere from a local business to a government agency. The scams happen in the form of mail solicitations with "amazing offers", emails with malicious viruses embedded, and marketing calls claiming to advertise your business for incredibily low costs; just to name a few.
Do you remember the last time you used a phone book? It was a convenient tool back in the day for looking up business listings because of those infamous "yellow pages". But now, since Google and Yahoo became popular, those days of thumbing through the book almost cease to exist. So why continue to spend money and effort into advertising in there?
