The Google, Yahoo!, and Bing search engines insert advertising on their search results pages. The ads are designed to look similar to the search results, though different enough for readers to distinguish between ads and actual results. This is done with various differences in background, text, link colors, and/or placement on the page. However, the appearance of ads on all major search engines is so similar to genuine search results that a majority of search engine users cannot effectively distinguish between the two.[1]
Brilliant stuff Brankica! This is a very comprehensive overview of major traffic generation strategies. My guess is that nobody will actually need to use all of them!

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.

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.
