If, on the other hand, you’ve already migrated to HTTPS and are concerned about your users appearing to partner websites as direct traffic, you can implement the meta referrer tag. Cyrus Shepard has written about this on Moz before, so I won’t delve into it now. Suffice to say, it’s a way of telling browsers to pass some referrer data to non-secure sites, and can be implemented as a element or HTTP header.
Google claims their users click (organic) search results more often than ads, essentially rebutting the research cited above. A 2012 Google study found that 81% of ad impressions and 66% of ad clicks happen when there is no associated organic search result on the first page. Research has shown that searchers may have a bias against ads, unless the ads are relevant to the searcher's need or intent 
The SEO landscape has changed enormously in the last years. Organic traffic comes and go, the websites’ performance seems to be as volatile as it gets and at the end of the day, you might ask yourself: why did my organic traffic drop? Did Google change its algorithm again? Was a sort of SEO attack on my site or was it something that I did? And while you keep on searching for the reasons your hard-worked ranks and traffic went down the drain, your frustration gets bigger as the solution to your problem seems increasingly far.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
You had to know social media would be on the list. I generally recommend that a site only have a presence on 2-3 social networks, at least while they’re small. It’s a lot of work to maintain, engage, and update a social network profile, and keep its messaging consistent with your branding. You can always spay someone to do it for you, but then it’s not a free traffic source, is it?
This traffic source comes from search engines like Google, Bing, and Yahoo. Remember, paid search ads or PPC (pay-per-click) advertising are not included within this source category. If you choose to run a paid advertising campaign for your business, it will not affect your website’s ranking within an organic search. Organic search is obtained through natural placement on search engine results, without paying for it, through search engine optimization best practices.
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.
