Search engine marketing is the area of the major search engines where businesses can list their site in the top spots as “sponsored listings” on a pay per click basis. This type of marketing has huge benefits for new businesses that want the best exposure on the search engines immediately. If you do a search on Google, MSN and Yahoo!, you will see the “sponsored listings” results at the top and sides of the free results. Pay Per Click advertising over the past 3 years is the largest area of growth on the major engines.
