Hi Does frequently answering questions on yahoo related to your niche improve your page rank on google and yahoo? Thanks -Rutuja
It used to a couple of years ago but not anymore. You can still get traffic to your sites using yahoo answers..Just post answers that adds value..
I think you should level up first by getting some best answers. Then every link you put will be dofollow that improves PR of a page. Otherwise they"ll be nofollow.
Yahoo Answers is dying, There are days (2007-2010) When people used to get a lot of traffic from Yahoo answers, Back then, they had a level system, when you reach a level, the links you leave were made hyperlinks (clickables) which made a lot of curious people click and land on the website. It doesn't work anymore because there are many other websites (Quora) that offer quality answers. Few people might be getting some traffic from Yahoo but I don't think there is any value given to the links in terms of the SEO (specially in Google)
Yahoo Answers also does not allow people to promote their sites, blogs, etc. If you do, you run the risk of having your account closed.
Since yahoo ans doen't allo you to put link now they are no use to seo neither they will give hyperlink so no link juice and hence no increase in PR of SEO
It doesn't improve your pagerank. All links are no-follow and, given the quality of Yahoo answers, Google is unlikely to place any value on links from them. However, Yahoo answers itself appears highly in search results. It's possible that you can gain a nice amount of traffic from the site and other similar sites.
It is not a effective means of advertising your website or increase PR. If you want a effective means to securing targeted traffic is with paid search, social media etc.
