Given the growing proliferation of real estate blogs, it is great that agents and brokers are finally realizing the incredible value of RSS. Back in 2005, I am proud that NeoRealEstate.com and PostYourProperty.com were early adopters of RSS in the online real estate world. Back then, I thought it would be a great quick way to allow users to subscibe to the feed of the posted properties by way of rss, opml, and atom. Of course, I wasn’t shy to rotate into every fourth posting position a text ad from one of our advertisers. Since my portals offer a free for sale by owner posting service with no referral or set up fees, I realized long ago, in 1999, when my sites started that eyeballs equal circulation. After 8 plus years, the ad based model continues to work. Affiliate marketing is still in its infancy.
