In early September, Google was up to something, and some spotted what looked like Knowledge Graph-driven facts being pulled into a web page’s search results listing.

Fast-forward to September 22, and it was official: structured snippets were now a part of Google Search.

But what are they? No, these snippets are not derived from structured markup on the page, nor does it seem that the facts showing in these snippets are pulled via a database in a Knowledge Graph-y type of way.
