A call to action (CTA) is a driving force - an argument - that motivates change and action. CTAs can be found in almost everything we see or do: "Sign up now!" "Follow us on Twitter!" "Buy one get one free." The reason for this is that a CTA promotes people to act and do something. When used in presentations, a CTA can be very effective or supremely underwhelming. You should understand your CTA before you start developing your presentation, but developing the CTA itself is already quite a process. So, in this SlideShare, we share with you the importance of a CTA, how to craft one, and how to deliver it in a way that helps the audience understand your message and act on it.
