I have written this paper providing step by step instructions on how to design your own banner ads.
You can pay $18.00 or more to buy a subscription based Banner builder. Or you can use free online Banner builders but it will include small ads inside the banner you create.
Or, your best option, Learn How to Make Your Own Banners using software that is probably already on your computer. That is what I do.
You can make any size Banner but in this tutorial I take you step by step through building a banner that is 468x60. This is the most common banner size for Traffic Exchange Sites. You can then build product banners for any product you want to promote.
If you are an ECA and you could provide SFI Affiliates with a nice set of professional banners that promote your products, do you think you could get a bunch of affiliates promoting your products all over the Net??? This tutorial will enable you to make those banners and get the promotions that your products deserve.
Hope it is a helpful read.
