A call to action in persuasive writing is a request to the reader to complete a task or work for a solution to support the position of the writer. For example, if the writer is striving to persuade readers to recycle, a call to action at the end of the piece may request readers to utilize recycling bins and stop throwing away items that can be recycled.
A call to action is designed to prompt the reader to do more than just read and understand the writer's position. A call to action shows the need for others to take action in support of the cause. For example, a call to action may ask the readers to write a letter to a member of Congress in support of a policy or funding for a program. A call to action may also request the reader to defend those in need by protesting or rallying in support of the writer's issue. Strategies to successfully employ readers to take action include showing the need for something to change. For example, the writer may remind the reader that it is his or her civic duty to provide for those in need or challenge a person in a position of power to advocate for others.
