The Inside Adsense blog reminds us about implementing ad placements that could inflate the incidence of click and miss.
They suggest three possible scenarios:
In close proximity to Macromedia Flash games Under pop-ups or download prompts Near site navigation controls on your pages, such as drop-downs or menu links
The last bullet might cause some alarm so most AdSense Publishers as this seem to be a common practice in ad layouts. I earlier blogged about “Adsense over-optimization could lead to click fraud?” and this could be related to that incident.
I think the rule of thumb here is that if the ads are placed in a position that it could be likely clicked due to slight inaccuracies in mouse movements then it’s possible to get your account banned for it. Hat tip to Chino.
Or, people could just focus on creating real blog-visit-worthy content. :-P
