Call to action is a handy tool for attracting your end-users attention with the use of images, text, and buttons, a popular choice if you want to advertise something.
A call to action could be a banner image without any interaction, or it could be an image with interaction, directing your end-user to click through to another page. Whatever the purpose of your call to action, it should be engaging, to the point, and avoid lengthy chunks of text.
