I don't like the Hostgator ad and I'm not sure it is a good idea for your site. People are usually looking for free templates immediately after finding hosting...so I wonder if this will perform for you. Also, having the phone number on the banner will definitely reduce your click-through, as it's designed to...if you have any options that way, I'd excercise them
Interesting design.. everything looks a bit too oversized though (except for your content's site). For your ad banner on top, I would move it into the upper content area because it looks like it's part of your site.. which is cut off (width wise)
