Troy asks in one of the comments about an easy way to make Google Sitemaps for his real estate website.
If you have a WordPress Blog as well as other Open Source blogs you can use a plug in that will make a sitemap for you.
For a regular ole website you can use my programmers fave which is: http://gsitecrawler.com/ . It will make a file for you and you simply place it on the root of your sitemap. Make sure to add the robots.txt "snippet" at the top of the file.
Sitemap: http://www.url.com/sitemap.xml
This robots.txt also goes in the root of your real estate website.
