I have read several threads, and it looks like if you have a customized K2 template the best way to get Google Structured Data is to add it to the K2 template yourself.

Can anyone confirm this?

Anyone know of any other ways to accomplish structured data in K2?

Thanks! -- Steven

Here is one of the threads I was looking at

Hello Steven,

The template is for K2 v3 but you it is really easy to c/p the microdata.
github.com/kricore/Advanced-templating-with-K2/blob/master/default/item.php

It is missing the organisation logo which should be added to your template directly.
