What do you think yahoo answers is better for? To rank your site or to make some direct sales by answering.
True, but in some instances. I myself have my own product, which I promote via YA. I have answered many questions, and because of this, my site has ranked higher, and the questions have too, so this equals more sales. That's the way I look at it. If you know how to use YA properly, then it can be very profitable, for any niche. Also, have a look at the question before answering. For example will 'Can anyone help, my PS3 just got a weird yellow light' rank? Possibly, but 'How to the fix the Yellow Light of Death', will generally rank better, because of the targeted keywords, so I tend to look for these questions. Do all this right, and you will easily see a consistent amount of sales per day! Dim.
Anyone who really had used the answers communities to a certain level before should know by now that they're just a waste of time/money. First of all your website can't rank higher since Yahoo answers is nofollow. (useless pretty much I'd say) Al.
Yahoo Answers are nofollow. If you want to get direct traffic, you can use that but not for gaining backlinks.
