As we mentioned before, when someone finds your site via a link on a social network, they'll be bucketed under social media as a traffic source. This could include someone tweeting out a link, or it could include you posting a link to your Facebook page. If it's you doing the posting, you can also add a tracking token before posting to track those links as part of a larger campaign for you to analyze later!

In other words, businesses have much less visibility into which keywords searchers are using to find them, making it much harder to understand which words and terms are or working -- or not working -- in their search engine optimization. Google said this would only affect about 11% of searches, but the truth of the matter is the number is much greater than that, and is only continuing to increase as Google's user base grows. It's important to keep this curveball in mind when evaluating organic search as a traffic and lead generation source.
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.
