Google claims their users click (organic) search results more often than ads, essentially rebutting the research cited above. A 2012 Google study found that 81% of ad impressions and 66% of ad clicks happen when there is no associated organic search result on the first page. Research has shown that searchers may have a bias against ads, unless the ads are relevant to the searcher's need or intent 
It might happen to have some lost links from now and then or a broken page due to some crawling issue or something similar. Yet, when your broken pages and links form up a figure just as big as your phone number, then you might be facing a problem; in terms of site user experience and organic traffic as well. Your bounce rate will increase, your overall usability, you will be loosing links and therefore you will start asking yourself “why did my organic traffic drop”?
The SEO landscape has changed enormously in the last years. Organic traffic comes and go, the websites’ performance seems to be as volatile as it gets and at the end of the day, you might ask yourself: why did my organic traffic drop? Did Google change its algorithm again? Was a sort of SEO attack on my site or was it something that I did? And while you keep on searching for the reasons your hard-worked ranks and traffic went down the drain, your frustration gets bigger as the solution to your problem seems increasingly far.
Yahoo Answers is one of my favorite traffic generation sources when it comes to answer sites. It has been one of my main traffic sources on a niche site for a long time, even after I haven’t used it for months. The main thing is to give your best when answering. If your answers are chosen as the best ones, you will have more respect in the eyes of the visitors so… yes, more of them will come to check out your blog.
If you check out some of the suggestions below this though, you're likely to find some opportunities. You can also plug in a few variations of the question to find some search volume; for example, I could search for "cup of java" instead of "what is the meaning of a cup of java" and I'll get a number of keyword opportunities that I can align to the question.
I would also advise to continue doing what works. If something you have rolled out generates great traffic and links bring out a new version of the content, for example the 2012 version worked effectively bring out the 2013 version of the content. Another effective strategy is to make the piece of content into an evergreen article which you add to over time so it is always up to date.
The term “organic traffic” is used for referring to the visitors that land on your website as a result of unpaid (“organic”) search results. Organic traffic is the opposite of paid traffic, which defines the visits generated by paid ads. Visitors who are considered organic find your website after using a search engine like Google or Bing, so they are not “referred” by any other website.
