Yahoo answers have become a major source of information for most of the people online who are searching for answers. This feature of Yahoo has unique answers from general users for all sorts of question one might be searching for, from the most casual one to the most complex.
The idea behind this feature is quite simple. People use search engines to find questions of their answers, but instead what they find is unorganized information. Searching within that information to find what you are looking for requires a lot of time, so Yahoo started this service which allows people to ask questions and then gets answers from the others, so that people could have information in specific question and answer form.
The idea for driving traffic from Yahoo answers is also very simple. You just have to search that section for your niche or topic your website deals in. Once you find a question whose answer is available on your website in term of a tutorial, product or service, you can safely post a link there and explain how it can help. There would be many advantages for this: It won’t be counted as spam, would be good for link building and also could drive some good referral traffic from there to your website.
In this way, Yahoo Answers could be easily used for driving traffic to blogs and websites.
