Yahoo! Answers is Yahoo’s response to the flurry of sites dedicated to peer-to-peer question and advice content. Other sites like Google Answers, and Just Answers actually cost money, while Yahoo’s is free.
While some of the content is of the bubblegum/7th grade variety, there are a lot more questions that deals with topics as simple as boiling water to as complex as phylogenetic cloning.
So what is the big deal? Well, since Yahoo! Answers, let anyone respond to the questions, there is an opportunity for you to promote yourself and your business by responding to relevant questions. This is a free way to get a little grassroots attention. Simply answer a question relevant to your business and in your signature line include a link to your website. Not only will the original poster see your answer, but so will everyone else. And an added bonus is the fact that Yahoo! Answers archives the responses, so if someone didn’t want to ask a question, but instead wanted to look up all the answers to similar questions, your response would still be listed, along with your tag-line.
This is grassroots, I know, but in the beginning, you gotta do what you gotta do. In response to me answering 1 question, I received over 42 hits to my site, within in 3 days. My website is not even finished yet.
