What is a CTA?
Every copy of writing must have a purpose, and that purpose has to be clear. CTA is the Call to Action, or to put differently, what you want your audience to do after reading your copy. An effective CTA is clear and concise. Use regular words. Talk to people like a friend.
A perfect CTA charms the audience into taking action because they are so convinced, they have no other choice. Give them a CTA they can’t refuse.
