The "Direct Session" dimension, not to be confused with the default channel grouping or source dimension, is something different. It can tell you if a session was genuinely from its reported campaign (reported as No), or if it was simply bucketed there due to the last non-direct click attribution model (reported as Yes). I didn't mention this dimension in the article because it has some flaws which can cause brain bending complexities, plus it goes a little beyond the scope of this article, which I tried to gear more towards marketers and non-expert GA users. It's certainly an interesting one, though.
For many startups, this means doing enterprise SEO on a small business budget, which comes with a few compromises. The problem is, Google doesn’t accept compromises when it comes to search optimisation and you need to get the fundamentals spot on. The good news is, the sooner you get these right, the faster you’ll be able to build a self-sustaining SEO strategy that doesn’t come back to bite you in the budget later.
You might see referral traffic coming from search engines like Google or Bing, a blog, newsletter, or email or social media sites like Facebook. Referrer traffic could be organic or through a paid search like cost-per-click (CPC) advertising or a paid advertising campaign that you have created (but in many cases, the paid advertising will show up in its very own Paid traffic type).
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.
