Don't just spam yahoo answer. Provide quality and relevant answers and then put in the link that you wanted to share. Just don't make your answers look too spammy. At first we do have problems regarding that. answering questions need some effort too by making some research about the question.
Don't post external links when you answer questions especially if your account is new. You can post your website in your profile along with other information. If you answer questions and are very helpful, people might start checking your profile and will see your website.
