traditional marketing strategy

I am a real estate agent and I am using the traditional marketing strategy. I am working in a real estate firm here in Chicago. I am 49 years old and I am having problem with my marketing strategy. I know I have many competitors and every client is a blessing for me. Since 2003 when the internet technology came over, I lost my charms and convincing strategy for my clients. It is because there are so many new ways to market and make a good deal online. At my age, I want to learn the latest trends in real estate marketing through online strategies. Please could someone from here help me out on this problem?
