Can I target with google?

If so...how?
EG: You can target what ads are seen on your site with YPN

 

If you're talking about URL targetting, I think it's impossible.

 

I mean keyword targetting....like I want game only ads to show up...instead of books...just an example

 

It all depends on your content.

 

so with gaming content, can I target to cars?
yes or no people?

 

No. That's why it called relavant ads.

 

I remember there is a method to do that by inputting certain code on top of the ad... but still, it is not recommended. I mean if the ad you're targetting is irrelevant, who is gonna click it? You will be wasting advertisers' money that way too.
