Below, there are text areas for each item to enter the text that will appear on the A-spot. Producer may add additional call-to-action buttons, up to 3. They usually create up to 2, as the front-end UI doesn’t look good with 3.
The label can be as long as 128 characters, and URL is either the URL after the base URL or external. Even if the content is not published, the A-Spots are created beforehand as the URLs are predictable. However, it doesn’t prevent the producer from making typo and publish the A-spot with a broken link.
