I have ranked many sites using this stretegy and with good keywords Yahoo Answers at http://answers*yahoo*com/ is an incredibly powerful tool for getting some pretty sweet link love to your site. With using this system there are essentially two ways you can get links that will not get you deemed a spammer. Method 1: This is a fastest method and works well but is much less effective then the second method. For this step you simply go to yahoo answers and click on "answer" on the top of the page. Next you browse the questions and find one that you know the answer to or have an opinion. If you can not find one right away, then click refresh on your browser... the questions are always changing. Enter a good quality answer and then underneath the post simply put your URL. You do not want to put a long URL and a great strategy here is to actually use your gather, hubpages or squidoo URL. This will help boost those pages which will boost your site. Do not put the site is the source area but just in the main answer area. Also do not use html, just put the URL. You can link directly to your site but so not use a long URL.. It can look spammy. Method 2: This strategy is very effective however it is a little more difficult. What you will do here is look for specific questions that relate directly to your web site. This is extremely effective if you have a presales letter or opt in on your site. How this works is first of all you take the market of your page you are promoting and search in yahoo answers. You will get thousands of results but the majority will be "Resolved' meaning you can not answer them. What you will need to do is look for questions that say... "Open Questions" Then you click the question and answer the question. If at all possible try to quote from your page and then put your URL in the "Know your source? List it here:" box. The better your answer the better for you because first of all people will search here for answers and if you answer will they may visit your site. Second of all if you have the best answer then yours is highlighted when the question is closed and you get more exposure. Now, the search engines seem to love this site, so far every question i have answered have been accepted and I have been awarded the best answer a lot. I also noticed that when I check my stats I get traffic from them, not a lot and it could be mainly search engine but it still is good traffic. VERY IMPORTANT - take your time and provide good answers. If you provide a crappy answer or just a couple words then you will get deemed a spammer and your work is wasted. As with anything, quality counts!
