I have found that social media marketing can be extremely overwhelming...and then discouraging...if you try to do too much at one time. Start with Linked In and maybe Facebook at first. Watch what other agents are posting and pick up some ideas that you think might work for you. Then develop your variations, to fit your needs. Be patient and ask other agents what is working for them. Almost always they are glad to share their successful strategies. You will get a lot of different responses. Assess all of it and chip away at it. You will soon develop your own style and comfort level. I am learning forever...
