Ad you can see on the right, the visual composer allows you to see what was entered into using the textual entry option from Part 2 above.
However, like the name suggests, you are abel to build your display ad directly in the visual composer. Simply ad whatever type of media you would like to display: video, .gif, picture, etc and ad whatever links you would like.
NOTE: Please make sure the type of media you put into the visual composer matches up with the size of the inventory slot (See Part 3: Target Slot). For example, if it is going to be a 300×250 inventory slot the inserted media needs to be 300 pixels by 250 pixels. That way it will display properly on your website.
