yes it's a new rule of yahoo answers. now level 1 users can't post links. yahoo is not so friendly like google. that's why it can't beyond google even it's a older company
I have a level 7 account on Yahoo answers, and I'm able to post live links. Being active on sites like yahoo answers, dose seem to increase the online authority of my business. But why limit it to yahoo answers? Dofollow forums is a far better route to increase online authority, since they pass on linkjuice at the same time. While the traffic quality of yahoo answers is both low-quality, and more short-term. Automated spam on yahoo is also useless, since such just make your business look like a fraud. Its very easy to tell when someone is submitting automated spam, or copy/paste answers. Quality answers, will on the other hand, contribute to peoples authority impression of your business, and that goes for forums, as well as article submission sites. Another thing to note, is that YA (last time i checked) dose allow us to post links to our own website, on a few conditions. And obviously you shouldn't just spam useless promotional messages, that will most likely just get you banned.
