i was just wondering about this the other day when i was on there. they dont allow direct links in your answer, but only "your source", which i think is no follow. HOWEVER, this might change if its picked as the best answer. its brought to the top and then i THINK its do.
I've done it once and everytime I inclused a relevant link to my website they gave me a warning. Also, while we are talking about links. Does this forum have a NoFollow thing? Just wondering since it would not increase the seo of any website linked to here in signatures etc.
I tried this but didn't really find any benefit to doing it. It's quite time consuming and you need to make sure you stay within their (quite strict) guidelines
Still works if you have a good quality site or blog, if now , if you are selling how to get rich then not.
A little tip: Yahoo tend to feature some of the questions in their SERPs. So, find out for what keywords they show YA, base your title on those and build links to those Q/A.
I don't actually spending any time searching on Yahoo! answers. But, I do get Google alerts, and if I get an alert with a question geared towards my niche, I always go and reply immediately. Not sure if it works wonders, but it definitely helps to get your brand out there.
