This is the benefits of an FAQ or open documentation platform. The treasure trough of organic keyword combinations and semantic linking that Google does makes for wonderful traffic. In most cases these are long-tail searches which evidently power >70% of all searches and from personal experience have a very solid conversion rate due to the intent of the searcher and relevant documentation in place to help answer questions.

For any startups out there, this should be at the top of your list for marketing. It will take time to get out of the Google sandbox but once you are out you are likely to get rewarded for the effort.
