Unless you have become extremely popular in your personal or business name, you likely need all of the marketing and promotion you can get. Now, you may say, of course, I'm aware of this, but who has the money? This a good and fair question. It may surprise you, though, when I say, you don't need money for some of the most valuable marketing available -- radio advertising.

If you aren't the kind of person who listens to talk radio, the next time you're taking a drive, tune in to one of your local talk shows and listen for awhile. Try to find something that is not a sports talk show, although they also offer the type of free advertising I want to explain. What you'll eventually hear is an interview. A talk show host will have a guest, who is an expert at something. Perhaps it's a health show, and the subject is weight loss and the guest is talking about some new diet.

Now, listen carefully, because you won't hear the guest babbling about his book, web site, or going on and on about his great product that is going to melt the pounds off of every fat person in America. What you will hear, in most cases, is someone who is explaining a method for weight loss that is a new approach. Now, at times throughout the show, this expert will certainly mention his product, and the host will ask the expert to tell the audience how to order it.

Even if you are an avid listener to these types of shows, and you've heard hundreds of guest experts, what you may not know is that in 99 percent of these cases, this is not paid advertising.

You see, there are thousands of talk show stations in America, and the ones that program only talk shows probably have five to 10 different shows per day. Some quick math will tell you that tens of thousands of talk shows nationwide need things to talk about and guests to keep listeners tuned in. This is where the magic comes in for you. As a new author, salesman or business owner -- talk shows need you.

Best of all, virtually anyone can get on a talk show. When I published my first book, Winning the Mortgage Game, I had very little idea how to market it, but I did know I was on a very small budget. I put up a web site, started an ezine, and it was an extremely slow beginning. That is, until I learned about being on radio talk shows. I read a very well-written how-to book by a man namedJoe Sabah about approaching radio producers and getting them to invite me to be a guest on their shows.

The second show I ever did was an hour-lomg interview on a station hundreds of miles away from my home. The producer called me at my house minutes before I was on, and the host began asking me questions about real estate finance. At various points throughout the show, he said Mark, tell listeners how to get your book, and I simply said go to www.winningthemortgagegame.com, and use the credit card of your choice. Believe me, people are much more apt to go to your web site, when they've heard you talk about your subject.

Now there are a few keys to getting on the radio and to making your appearances turn into sales of your product. First, you need the names and numbers of the stations and the producers of the shows. Remember, producers book the guests, so they are who you want to talk to. When you get them on the phone, which is not easy, be sure you are prepared. Don't just say you want to come on and talk about your new book or product. Start by telling them you are an expert in whatever the relevant field is and that you have a new system you want to share with their listeners.

Remember, this is going to be a lot like sales. You need to talk to a lot of producers to get a few bookings. Not everyone is going to jump at what you are offering. Make sure you speak in a good voice, so the producers think you'll sound good on the show.

When you do get booked, be sure you have several key points that listeners will remember, and make certain they know exactly how to get your product. Incidentally, if you want to get a great list of radio stations and their contact information, look for Joe Sabah's book. Radio talk shows are one of the best free ways to advertise you'll ever get. Take advantage.
