I am on this "mission" to find every FREE way to market myself and my website. I have found that Google offers a free business ad on their Google Maps. The way it works is you create an account and then an ad for them to run. If someone types in "San Francisco Real Estate Agent" you name will come up on the map with an arrow to where you are located and give the user your contact information and website to visit. I don't know the exact numbers as to how many people click on this but it's offered at NO cost!! They also have another section that you can create a coupon and they will display it to the right of your business ad. I currently am offering 50% off staging. Users can see that and print it out or email me in regard to that promotion. Below are the links to sign up and a link to my actual ad so you can see a "live" example. If you have any other examples to advertise on the internet for FREE I would love to hear them.
