Are you using banners instead of endorsements?

I know. It takes time, effort and money to buy and study the product you're trying to sell. It's much easier just to cut and paste a bit of HTML code. However, personal, enthusiastic endorsements out-sell everything else by miles. If you put in the effort, you'll get the sales. You can probably quadruple your sales by endorsing the products you sell. You can also combine graphics, text, short descriptions and relevant articles. However, best of all are your own, original personal endorsements. Write honest, enthusiastic endorsements.
