7-fold increases in a couple of days? Wow, I better get going on this! ;-)
For those who don't want to register at WMW to read the forums, basically, people have been reporting immediate results with multiple times increases on their CTR.
My take on what ASA says is that using pics in itself is not against policies but you can't directly encourage clicking for the sake of clicking. It's gray, I know, but an arrow image pointing to the ads may not be ok while a pic of a smiling young woman on top of an ad seems to be ok, even if unrelated.
