As you probably know, sitemaps are important for making sure your site can be completely spidered and indexed by the search engines. Unfortunately, many of these sitemaps are specific to one search engine or another. For this reason, there have been a number of Google and Yahoo site map generators produced in recent years.
However, there is an alternative that is even more exciting. These are ROR sitemaps and they are readable by all search engines, not just by Google or Yahoo.

ROR is an exciting new sitemap tool that uses XML feeds to describe your website. These sitemaps are structured feeds that enable search engines to complement text search with structured information to better interpret the meaning of your site. With a ROR sitemap, search engines can better understand your products, services, images, newsletters, articles, podcasts, and anything else that you want to describe.

For example, if you are selling products, a ROR file enables you to document your product names, descriptions, prices, images, availability, affilíate programs, and any other relevant information. Search engine crawlers like the Googlebot have an enormous job to do. It’s time we start helping them to better understand our content.
