Changes in Amazon ads

[Carmel]

I recently put together a new ad on Amazon, using keywords. In the past the ads have required a short description or blurb to capture interest. This time it did not seem to have a prompt or place for such a thing. Did I miss something, or has Amazon taken this option away? Have any of you experienced this yet? Is there a way to still provide such a thing to encourage those clicks? I've been seeing ads in the sponsored lists that don't provide any descriptions of the books either. Any ideas or experiences to share?
