There are also member level with points given by yahoo. As your level increase you can also leave a link in your signature of answering posting.
I used yahoo answers in the past mainly to get targeted traffic by answering questions and helping people. I do not think though that YAHOO ANSWERS is very helpful with SEO or building links but it is more niched towards bum marketing.
Google used to index Yahoo answers very quick but not anymore. Lot's of people spamming Yahoo answers therefore Google only shows answers from past years which didn't delete by Yahoo community. Yahoo answers doesn't have big SEO effects but it is always good place to create traffic source for your site by helping the community at there. If your answers selected best answers, it also gives good traffic in the future
You cannot rely on yahoo answers, there are many self promoters and spammers... however it a good place for online promotion.
Yahoo answers are helpful to get knowledge as well as also for getting traffic. Yahoo is one of the best and very popular site, so it is also a great place to redirect quality traffic to any website.
Yeah, Yahoo Answers is pretty awesome when it comes to SEO, also it's helpful to gain knowledge and information. Quora is also a website to know things about life and everything in general. If your answer is accurate, to the point and liked you can direct the traffic to your website as well.
Ive used in the past. I provided value in my answers but in the long run I still got banned. I wouldn't use it now as sooner or later YA is going to catch on.
It was a very strong way to get GREAT number of visitors daily if you are active, nowadays full of spammers. Not recommended any more if you want to promote something!
I've noticed that too. Before when I searched something on the web google was still able to pull information from Yahoo Answers but now I don't see YA anymore on SERP. For some, it is a great source of traffic (and also backlink) though I wasn't able to prove it because it really takes some time and effort to be a reputable contributor in YA. Anyway, I'm wondering what do you mean by "how helpful?", in what aspect??
by putting your site in source box you will get good traffic to your site. Find questions related to your site and post answers.
YaHoo Answers are cracking down hard on links. I haven't been able to complete an order for this particular listing in a while. They've increased there moderators and they are heavily watching for anything that smells of spam. Be careful. My account hasn't been banned or anything like that, but they are watching for this sort of thing quite hard.
