Some promotions don’t need any configuration (e.g. search results priority, boxed & highlighted listing, and bold listing), they just appear the moment you add them to your business listing.

Others (e.g. customize my listing, and create my website) require some configuration before they appear in your listing.  Once you’ve added these promotions to your listing you’ll need to configure them, and you can change and update them instantly at any time as often as you wish.
