Google Search Starts Rolling Out New Preview Markup in SERPs

[engine]

Google has said it'll be rolling out the new preview markup in its SERPs, and it'll be fully rolled out by next week.

Previously, it was only possible to allow a textual snippet or to not allow one. We're now introducing a set of methods that allow more fine-grained configuration of the preview content shown for your pages.

Looking forward to this. I have high confidence a stupid site owner is going to need help after they block their snippets and then wonder why Google isn't showing them in the SERPs.
