Do you find you're answering a lot of the same questions for prospective buyers and sellers? Why not create a video or write an answer to these topics, then post them on your site?
If you're going to video, make sure you have a high-quality Webcam with great audio. Michael Krisa (That Interview Guy) of
RealEstateUnplugged recommended to me the
Logitech 9000 and I love it - not only is it easy to use, but it's also very affordable!
So an example - lots of sellers are now asking you, "How does a short sale work?" Write yourself a quick script, record the video, and post it on your site. Write a blog about it (keyword rich for the search engines) and embed the video. If you don't like doing video, then write an article on it, post it on your blog, and then add it to a resources section on your site content.
