If you blog to promote your business, then I recommend a visit to hubpages.com.
Hubpages is a community of writers and readers who publish 'hubs' on almost any topic. You can earn $ via adsense, ebay and amazon affiliate progams that are built into the free hubpages membership.
While I DO NOT recommend writing blatent ads and publishing them, you can offer helpful advice, tips and your experiences in your area of business and collect some valuable readers, fans, traffic and exposure.
