@anirban09PMay 19.2014 — #Words that urge the reader, listener, or viewer of a sales promotion message to take an immediate action, such as "Write Now," "Call Now," or (on Internet) "Click Here." A retail advertisement or commercial without a call-to-action is considered incomplete and ineffective.
@omthavertchMay 31.2014 — #A call to action, or CTA, is a banner, button, or some type of graphic or text on a website meant to prompt a user to click it and continue down a conversion funnel.[1] It is an essential part of inbound marketing as well as permission marketing in that it actively strives to convert a user into a lead[2] and later into a customer.
