I'm using banner offers for very targeted traffic, getting a CTR of 0.23% for this month with over 100,000 impressions. This is pretty standard from month to month. Yet a grand total of zero sales. What am I doing wrong? I'm running the banners on a blog within posts and on the sidebar. And they're all directly targeted to the visitors of the blog. I've searched and browsed on here for ideas, but most everyone's CJ methods seem to be different than just sticking banners on a blog. Any advice?

Try placing the banner at the top. Take some of the aff links and place it within the post. This is a placement issue it seems.

I would say have interesting items for sale and have them at top banner sort.
