Previously, we (Google) only looking at content from the HTTP response and didn't interpret what a typical browser running JavaScript would render.

…When pages that have valuable content rendered by JavaScript started showing up, we weren’t able to let searchers know about this content, which was a sad outcome for both users and webmasters.

In order to solve this problem… we started executing JavaScript.

In the past few months, our indexing system has been rendering a more web pages like an average user’s browser (with JavaScript turned on).

JS-Googlebot now indexing JS content!

4. It will eventually supersede microdata
