What about YahooSearch, Microsoft adCenter, and others as less expensive pay-per-click alternatives to Google Adwords?
A. Most of my clients who use Google Adwords also use YahooSearch & Microsoft adCenter as well. Heres the thing though. The COMBINED search volumes of Yahoo and MSN for most keywords are only about a third to a fourth of Googles, and in many cases the click prices for their respective PPC services are simply not that different than Adwords (besides the fact that Adwords is a light-year ahead still in terms of usability and data provided). Sometimes YahooSearch and Microsoft adCenter are more expensive and sometimes less than Adwordsbut are usually pretty comparable. There are also other lower tier search engines with PPC options, and if if those engines are targeted toward your audience(s), they could also be worth a try.
