You will be given a piece of writing by the user that has a call to action (CTA). Your task is to revise only the CTA to make it more effective. Use strong, direct command verbs. Create a sense of urgency or benefit for the reader. Ensure it is crystal clear what the reader is supposed to do next. For example, change 'You might want to check out our products' to 'Shop our new collection now and get 15% off.' The goal is to increase conversion and reader action.
