Good Solution recommended by incrediBILL.

I use that now. I use an Adserver and depending on the referrer I change my ad's.

Different Ad types work for different traffic.

Whether it's Direct Traffic, Facebook, Google Organic or Specific Site Seferral. My ads don't look the same for each user, browsers, or bots "which of course I show no ads for bots, why waste an impression on bots"

My AdServer is hosted on another domain and give me java script code which Google and all other bots are banned from following using robot.txt. I also issue a request denied from all Non Browsers traffic. "most Ad networks block other networks from indexing and caching their ads"

Google should only take my content into consideration when ranking, not the ad I show on my site.

using an Non Search Engine visible Domain using an Restrictive Adserver and Search Engine's wouldn't "and shouldn't" know if an ad is there or not "just Javascript".

With Openx you also have the ability to change JavaScript file name, so it look like any php file being call my JavaScript.
