Google Base has been around since 2005. I have been in the real estate business for over 3 years and just now hearing about it being used for real estate. In my area there are over 13000 listing on the site. All these listing were free to add to Google Base. They will also appear in the regular Google search page. This is a big step in getting your listing on the internet. Companies like Keller Williams Realty in Corona California have already inked deals with Google to have all there listing taking from their Keller Williams Listing Service site and advertised on Google Base. Other companies are now fallowing in their foot sets.
Google Base can also work well for For Sale By Owners. This search site always buyers and sellers to get an idea of what’s in their area. You can narrow your search to zip codes or cities. The down side is that they are not teamed up with the local MLS systems just yet, so you want get all the listing available. But this is a deal that will have to be made by the local MLS at some point in time. It would give every agent more exposure for their listings. At this point Google, Yahoo and Trulia.com are the top 3 sites for agents to generate clients.
So take the time and sign up for an account at Google Base and tell your new clients that you will put them at the top of the Google Search Engine.
