Below is a screenshot of a Kontera ContentLink ad gone wild
Sweet, Kontera tells us how we can get coupons for our heroin addiction at CouponMountain.com. I don’t this would qualify under Google’s terms of service, as they disallow advertising for all illegal substances.
The Click Through Rate for this ad may be high so CouponMountain.com could be experiencing increased clicks on their ads. The traffic quality is most likely very low and probably results in a high bounce rate.
