I also suggest to make use of the "advanced" search option. Through this, find a question related to your site and give meaningful answers. Then if you happen to have a particular article about that, put it as your source..
it used to be good. I spent some time finding questions related to my niche and answered them with a link to my site. I still see some hits coming from Yahoo Answers, but absolutely not worth the time spent.
Exactly what happened to mine ..but nevermind i like to participate to answer question for fun. I don't know i just feel like to give out what i know.
One thing that i don't like in Yahoo answers is the Suspension of your account from the Service with no reasons that are reasonable. It may only your competitor who reported it abuse but that's being unfair if you really know that you're abiding their rules.
To this day I really don't know why some people will select "Yahoo Answers" for their marketing efforts. It takes a lot of your time for little returns and if not done correctly people will assume your submission is spam upon given reference to your website. It's very different from forum marketing, seriously consider avoiding it. There are much bigger/better advertising methods that give you better returns. My experience
