Please help to review my <0.5% CTR adsense page.

This page has been in Digg's frontpage. Though digg's traffic is gone, often some other sites e.g del.icio.us bring nice traffic to this page. But the CTR is very poor,below 0.5%. So I tried to replace the ads. But I don't have much experiences on this. Please help to review, thanks.

i got 50% of my traffic from digg, even when i am not at front page.
there is no ad at the beginning of your post
images with Ads? this is a risk for losing your adsense account.
1 link unit at top box

 

The people from Digg and Digital Point and the like will normally not click on ads. They are going just to see the story.

As the above poster mentioned, you better remove those picturs next to your Google Ads

 

It's againast TOS? But I see many sites use this kind of images.

 

Thanks mani. I've added a link ad on the top.

 

Removed the images to avoid the risk. Thx.

 

The styling is totally unclear. I'd tone down the adsense to blend more, especially that big block halfway through your content. If you have a unit in a navigation-area, make the colors similar.
