There are few different ways to get Salesforce KnowWho Actions on your page:

• National Action Trio -- this actually is not limited to National Actions, and we'll be changing the name of this
• National Action
• Local Entity Action - this is essentially the same as National Action, and I may at some point consolidate these two. The first two "National" Actions, try to do work to replace the action if it expires or is unpublished with another similar action.
• KnowWho Iframe - this replaces functionality for AddUp. More details below.
