'"Natural traffic" isn't a term that's widely used in SEO. In fact, I'm not sure I've ever actually heard it used--ever. "Organic traffic" derives from "organic search results", which were originally the algorithmic, non-paid search results before there was Local Search. Organic traffic is that traffic that comes to your site from non-paid, search results (and technically, also not from Local Search--although that might be debatable.)
I’ve always been a believer that hard work gets the best results, and in practice it always ends up being true. On the web it’s no different. If you want more organic traffic, you have to work for it. That means giving your best effort every time, going after opportunities your competitors have missed, being consistent, guest blogging strategically, and staying on Google’s good side.
One of the great things about online content is that it can always be updated and expanded. While you should be strategic in your content creation, you can also think about blogging as an opportunity to test new ideas. You don’t have to make every post perfect and comprehensive right from the start. As your experience with and knowledge of a particular topic grows, you may have opportunities to return to older posts and improve upon them. Or as the industry evolves and customer needs change, you can update your content accordingly. Not only does this give you updated content for search engines, it shows your readers that you’re on top of trends in your industry and that your website content is fresh, and therefore trustworthy.
Secure (https) to non-secure sites (http): Since Google began emphasizing the importance of having a secure site, more websites are securely hosted, as indicated by the “https” in their URLs. Per the security protocol, however, any traffic going from a secure site to a non-secure site will not pass referral information. For this issue, you can correct by updating your site to be secure through a third-party SSL certificate.
Plan your link structure. Start with the main navigation and decide how to best connect pages both physically (URL structure) and virtually (internal links) to clearly establish your content themes. Try to include at least 3-5 quality subpages under each core silo landing page. Link internally between the subpages. Link each subpage back up to the main silo landing page.
