Hi. Here's my site: http://conradmiguel.com/. On my blog, a large rectangle ad block randomly (3/5 probability) appears between the post title and post entry when viewing the post page. Here's another site of mine: http://pshsfirstscreeningresults.conradmiguel.com/. It's a school admission screening results page. Try browsing to see my other ad blocks. What do you think? I'm getting a very low CTR.
