The other way visitors can access your website is by coming from other websites; in this instance, the user lands on your website after following a link from another site. The link that the user clicked on is referred to as a “backlink,” as it links back to your website. This traffic is much more beneficial to the search engine optimization (SEO) of your website as opposed to direct traffic, which has little to no effect. The reason is that Google and other search engines interpret backlinks as little doses of credibility for your website. If other credible websites are linking to your site, that must mean it is comprised of relevant and accurate content, which is exactly what search engines want.
Looking back at our lab site, we can see that Organic Search is doing well for us. However, if we put a little effort into social media, we’d probably see growth in that sector — and a bigger pie. We’ve got some strong referrals (and high quality links that improve our search presence), but if we put some work into building more of those links, we’d probably see more referral traffic and, again, a bigger pie. Should we add paid search? For this site, no. It’s part of our community service and has little revenue potential, so we wouldn’t see much ROI from ads.
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.
