Selecting “All Traffic Sources” from Google Analytics left-side navigation will show you a table listing the most active traffic sources and their medium. Direct traffic, as you would expect, has a medium of “none.” Traffic from Facebook, as an example, will have a medium of “referral.” Search engine traffic will have a medium or “organic” or “CPC” as described above.
Organic traffic is the primary channel that inbound marketing strives to increase. This traffic is defined as visitors coming from a search engine, such as Google or Bing. This does not include paid search ads, but that doesn’t mean that organic traffic isn’t impacted by paid search or display advertising, either positively or negatively. In general, people trust search engines, and sayings such as “just Google it” reinforce that humans are tied to the search engine. Thus, paid search, display, or even offline campaigns can drive searches, which may increase organic traffic while those campaigns are running.
Forums are probably one of the least effective forms of free traffic, but it all depends on the forum. You’re looking for large, active communities where you can carve out a bit of a reputation for yourself. Sure, you can dominate a small forum, but the returns won’t be worth it. Conversely, too large a site and you may have trouble attracting attention at all. It’s a hard balance to strike.
Understanding where your site visitors come from is an integral part of any marketing strategy. Your website is the heart of your digital marketing practices, with traffic acting as the blood. No traffic means your website can’t do anything for your business; knowing the different kinds of traffic and how they play into your website gives you the power to make educated decisions on how to improve your marketing practices.
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.
Organic is different. Matching keywords to user intent means you may be present in many searches. The user may find you consistently, and once they get to your site, they are more likely to stay. Organic users are still your best long-term customers. In my experience, they have lower bounce rates and more pages visited, and they are more likely to return.
