AdSense helped boost our number of daily visits when we experimented with it, but we've had much more success getting traction other ways. Once we stopped advertising the boost subsided. We get better kick for the buck directly sponsoring private forums with decent niche traffic. We will probably experiment with higher value keywords at some point. The major issue is mostly conversion rates though - you need to charge a high price to justify spending a significant amount to attract one paying customer. SEO is a much better approach, but it's interesting to see Google getting taken to the cleaners here by some of the more spam-oriented sites out there that really push the keywords into their domain names. Even the market leader in our field is not listed on the first page for the most important keyword related to their product.
