Hello guys, it's been a long time I didn't use adsense and I want to create some autoblogs so I've got some question.
I've seen in adsense that some keywords pay well (like auto insurance etc), if I put these keywords in my site (in blank so nobody is gonna see them) to get the ads that pay well, will I get banned?
Also, do the people click the ads because they are interested?

What I mean is am I autorized to put ads that don't belong to my niche?

Yes my friend Welcome back as i feel you have not been here for a while!

To answer your questions -
1. Yes, you will be banned if you put your ads like you described.
2. People click on the adds because they are placed in areas where they can read about what they search. That means - content + adsense adds working well and Yes, because they are interested in your website content.
3. As adsense delivers related ad content to your wesbite content - i do not understand your third question.

Any way - If you want to work with adsense seriously I would not suggest ANY cheating! As sooner or later they will catch you and they will ban you....and trust me - it's painfull
