Never assume your customers know what you want them to do. You have to make it fool-proof for them. You have to spell it out for them – in black and white. Think about it like this: first, the customer reads your copy; then the customer does “X” task. X task is what you want them to do – perhaps it is for them to call your office or it could be signing up for your e-newsletter. Whatever it is, make it clear and simple. You don’t want your customers guessing. It can also be helpful to include some sort of time frame in special offers. This can help motivate your customers to act quickly. An example of this would be, “Today Only 25% off your purchase.”
The more specific your call to action … the more likely the customer will do what you want them to do.
