(from source) - "In web design, the button and wording on a page that asks you to “click here” or “sign up” is known as the “call to action” (CTA). It’s a plea for the user to do something and good designers make these calls-to-action appear to be the default choice – you’re nudged to take action through clear layout, positioning of the button, use of colors and so on.
The term is also used in advertising: “for a limited time only”, “while stocks last”, “a once in a lifetime offer”. These are all calls to action to get you to do something now and not put off your decision.
A transmedia experience needs similar CTAs to get audiences to cross platforms. See also Call to Action Loop
