SEO RETS integrates RETS data into WordPress. This WordPress RETS plugin pulls the data at least daily and more times depending on the MLS board and provides that data to your WordPress website. You do not need a RETS server, just a regular WordpPress website. It is Godaddy and Bluehost hosting friendly, meaning you can use their hosting for your website. The data is extremely accurate unlike third party aggregation sites like Zulia (Inside Joke).
