The timing couldn't be better for the release of Semantify, a new service from San Francisco's Dapper.net. One week after Yahoo! announced that it will begin indexing the semantic markup and meaning of content on the web, Semantify offers a remarkably simple way to get your website marked up semantically. Automatically, forever.
Once you learn how to use Dapper's basic interface, it can take less than five minutes to set up the Semantify service. Hello SEO, 3.0. rww
