"Google Base" is a name you'll have to get used to hearing in the real estate world. It's the latest foray launched by Google, in what many experts feel is the end of newspaper classifieds.

In short, it's database that people can use to post stuff, ranging anywhere from photos, recipes, garage sales, and property listings.

As an real estate agent, you can post your property listings on Google Base for free. Actually, it's free to anyone. You can write up some descriptive text, include a photo, and specify keywords like "las vegas homes for sale" or "omaha real estate", etc.

Once posted, anyone can search it by keyword to find whatever they want.

Each "ad" you post on Google Base lasts for no longer than 31 days, after which, you have to post it again, if you want to keep it online.

Many companies have already produced software products designed to automatically post content into Google Base. RealBird Inc., which provides Realtors with mapping services for their websites, says they've added a feature that automatically uploads an agent's featured listings into Google Base.

While Google Base is free, many expect the search engine giant to start charging fees.
