Hi Chris, the trick is to have different names leading to the same site. I have about 11 names, within them, can be a microsite that they click on that was their intention. They will see what they came for when they get to the blog.
I do have individual blogs that link to each other which gets extra points. They tend to be area, subdivision, recreation, statistics, listings etc. An easy way is to set them up per zip code and pull off of existing statistics, demographics etc. I find zip codes are easy to get stats on.
We are experimenting with a listings only blog where we blog of all of our listings and keyword optimize them and put them o U-Tube, Flicker, Photobucket, My Space, Facebook etc. I have actually found some of my listings show up on Google, it is exciting sometimes.
I have a great source for a professional looking blog. He is less than 500 dollars and does SEO on it, it looks like a website. Feel free to check it out at http://www.renohomestalk.com
keep in mind we are still working on it. It is about 1/3 complete.
