targeted advertizing is when a certain audience is targeted to view commersicals. For this example, I have to quote my sfr teacher:
Quote
Let's say you wake up at 9:00 in the morning, and you're waching... umm... flaming donkey cartoons, and an advertizement comes on for... umm... sugary sugar o's... "hey kids, buy shugary sugar o's they're good! dat dat-dat dat dat!" and you change the chanel to CNN moneywacher's boring stocks, and an ad comes on for a loaning agency. Most of the viewers for the donkey cartoons would be kids, but the boring CNN thing would be investors and stuff. They target those audiences. You wouldn't expect to see a loans ad on flaming donkey cartoons, and you wouldn't see an ad for sugar o's on CNN.
Google ads (and their "clones") work by targeting you, the viewer of an audience (let's say trap17) with an ad for used 1985 home computer crap. You know what I mean? so now you know how google ads work.
...btw, my sfr teacher is awsome, I just had to quote him...
