When at all possible, answer the questions first, the first answer is directly under the question, anything else and you could find your answer and link buried under others. Make sure you give the best answer possible, being voted best answer ensures that your answer will stay at the top and generate marketing from it. When people post a question on Yahoo Answers, Yahoo searches for the Question as well as the people posting and others will read the best answer over some of the other ones. Think of it as a Search Engine and you want the top spot. Try to become a top contributor. This is accomplished by answering questions, posting questions and also by getting those best answer votes. Having a high rank means people are more likely to trust your answers and thus your website. The more you hit the top mark the more traffic you are generating.
If there isn’t a question that is tailored enough for your website or post, ask a friend to post a question for you and then vote you as the best answer. If you have multiple IDs, you can do this on your own, but remember people and the system can catch spammers and fakes. You want to increase your marketing and not take away from it by a bad Yahoo Answers post. While searching the questions to write about, you can use the star it feature to keep track of questions you are interested in. Also check out the Yahoo Answers International, here you will find locations from around the world and create even more hits from a larger scale.
