I think there’s a little more to it than what’s been discussed so far. The mechanics of how Adsense works, in isolation, is not enough. In the end, an ad has to be catchy and well written. In one word, it has to be: Enticing – ads must catch consumer attention. This is true in B&Ms and virtual stores. In this case, you want something that’s catchy enough that users then click on that ad. Some standard tactics sellers use, include using the words “free” or “buy one get one” or “discounted” or “sale.”

You can use Adwords itself to review terms. Ask yourself: What catches your eye? What gets a reaction? This helps build a list of words that you can use to write an effective ad.
