At about $0.85, yesterday's average cost per click (visitor) for Google Adwords was the lowest I've ever seen.  Usually the national average (from our perspective) is around $1.65 per click.  Looks like Google may be feeling effects of the mortgage and real estate industry woes. 

If you've ever considered search engine "Pay-Per-Click" (PPC) advertising, now may be the best opportunity for you.  Just make sure to not get wrapped up in the bidding war for top position.  Set and stick with a modest budget, letting the top bidders expend their resources first.  There will still be online buyers available when the cost per click lowers to the amount you've agreed to pay.
