Google Adwords is one of the best tools for small business owners looking to drive traffic to their web sites.  Google is the most-used internet search engine on the planet and many online publishers place Google ads on their sites to earn revenue.  For advertisers who are uncomfortable with the thought of relying on Google for ad support or who want to include other ad companies in their campaigns, there are Adwords alternatives who offer good service and decent reach (although not the almost global reach of Google).
