Chapter 3: Banner Ads
You can create your own banner ads by using a simple program such as Paint.net. The most common size for a banner ad for an ezine is 150 to 175 pixels wide; they can be square or rectangular.
You don’t want to use too much text on your banner and not too many colors either. Your call of action such as Sign up for Free should be highlighted in a different color and easily visible.
If you don’t want to create your own banners you can use online software banner creators or use a site like Fiverr and hire someone to create one for you.
