Hi Brankica, I'm a total Kindle addict too! As much as I love to hoard books, the Kindle makes it even easier to consume books in volume! One other suggestion: There's a nifty new service called http://paywithatweet.com that allows you to give away an electronic download in exchange for a Tweet or post on Facebook. I LOVE this and have been testing it out with my latest book. Very effective!
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.
