Where it appears

In Where it appears choose The whole site or Only the pages chosen below:

• The home page;
• Every page of these types: pages, posts and the public types of your plugins;
• These pages: one per line, the address of the page, its path (/contact/) or its ID. A * at the end takes every page that starts so: /blog/*.

Never on these pages uses the same format and wins over everything else: put your checkout or account pages there.

These rules are applied by the site when it builds the page, so they work with page caches too: a cached page is the same for everyone at that address.
