But how many people are going to to an "organic" search of your exact home's address??? Is that realistic? Probably not. I assume you are trying to attract more buyers? I would suggest you find out what your Realtor is doing to expose your home to as many buyers as possible. By having the listing syndicated to all of these websites, is a good start. But you also want it to show beautifully in photos. Did your agent hire a professional photographer? And how is the price? If it's priced well, and looks great, and appears on all the major websites, then you shouldn't have a problem selling it.
