One possible strategy for Google is to stop messing around with the seven-pack on queries like "Houston Pizza" and start selling the AdWordsGroupon among Houston Pizza shops at the top of that search result. This takes the AdWords learning cliff out of the local retail sales equation, because retailers grok "Check this out: you give us a big discount, we will sell your stuff, then we give you a check for this much and you service people who come in with a coupon -- no money down and no risk!" much more than they do "OK, so you front us a couple thousand dollars for CPC ads and if your QS outperforms competitors in the local auction for the query string, match options dependent, then as long as your CTR is decent we'll send the user to your landing page and you might achieve a conversion which if it has a CPA less than your LTV is a win for you. P.S. If you don't understand that, Pizza Shop Owner Guy, Google Customer Service says to FOAD."
