This is a very good question, but by now I am sure that you have enough examples of keywords to use in ads.
Now I want to bring it all home so you have the best chance of bringing in affiliates with your ads. In all the Ask SC answers I have read for this question, I still have not seen anyone bring up Key Codes and Hit Tracking. All of the best keywords do not mean a thing if you are not tracking your progress.
You need to track your progress with your ads using Key Codes and Hit Tracking!
If you are not it really is a crap shoot as to what is working, when it is working and where it is working. This is the ONLY way you will find out if certain keywords are in fact keywords.
Familiarize yourself with Key Codes and Hit Tracking, they can both be found under the tab "Power Tools", and your success rate will increase ten fold. Keep what works and discard what doesn't. I hope this helps.
