Google (GOOG) to move AdWords to wireless search

Google (NASDAQ: GOOG) is betting that search on wireless handsets will become a big business. The company understands that online search on the PC platform cannot grow at its current rate forever, so, at some point, revenue from its AdWords program will begin to flatten.

To combat the potential of a less robust growth environment on the web, Google is moving Adwords onto its Google Mobile Search product. The program will be free until November and ads will only run on websites designed for handset screens.

Silicon Alley Insider points to a recent survey by research firm Kelsey Group as the reason Google is so anxious to get a foothold in the new market. "Revenue from U.S. mobile search advertising will soar from $33.2 million this year to $1.4 billion in 2012."

Google has some potholes in its path. After being handily beaten in the PC-based search market, Yahoo! (NASDAQ: YHOO) and Microsoft's (NASDAQ: MSFT) MSN Live Search are working to get their products on as many handsets as possible. However, they still have the disadvantage that their search products do not produce results as good as Google's and their text ad targeting products are inferior.

In moving to the mobile platform world, Google maintains its critical edge.
