Thanks for the comment Slava good too see your team is on top of things and happy you liked the post. The website in the case listed was a client who has taken on an agency who was doing lower quality SEO work which was affecting the site such as the huge link network and a strategy which only revolved around mainly head terms. We saw no long tail integration from the old agency's strategy, so we were able to yield great results to begin with. The clients site has 100's of high quality articles which we were able to re optimize and update as noted. Further to this they had a large index of high quality pages to work from. Sure enough the points listed above were key elements to a far wider strategy which could be 100's of points. I just wanted to include some of the biggest wins and easy to implement points.  

If the blog post you’ve selected has less than 2,000 words, one simple way to increase organic traffic is to increase the word count — but don’t just fluff it up. Make sure any content you add also adds value. Instead of watering down paragraphs, add completely new sections that cover points you haven’t introduced yet. Chances are, the added word count will allow you add additional keywords. Speaking of…

Let’s say you wish to block all URLs that have the PDF. extension. If you write in your robots.txt a line that looks like this: User-agent: Googlebot Disallow: /*.pdf$. The sign “$” from the end basically tells bots that only URLs ending in PDF shouldn’t be crawled while any other URL containing “PDF” should be. I know it might sound complicated, yet the moral of this story is that a simple misused symbol can break your marketing strategy along with your organic traffic. Below you can find a list with the correct robotx.txt wildcard matches and, as long as you keep count of it, you should be on the safe side of website’s traffic.
Otherwise you might end up polluting your website’s traffic. The pages filled with obsolete or low quality content aren’t useful or interesting to the visitor. Thus, they should be pruned for the sake of your website’s health. Low quality pages may affect the performance of the whole site. Even if the website itself plays by the rules, low-quality indexed content may ruin the organic traffic of the whole batch.
It's a little awkward, so we'll get straight to the point: This Monday we humbly ask you to defend Wikipedia's independence. We depend on donations averaging about $16.36, but 99% of our readers don't give. If everyone reading this gave $3, we could keep Wikipedia thriving for years to come. The price of your Monday coffee is all we need. When we made Wikipedia a non-profit, people warned us we'd regret it. But if Wikipedia became commercial, it would be a great loss to the world. Wikipedia is a place to learn, not a place for advertising. It unites all of us who love knowledge: contributors, readers and the donors who keep us thriving. The heart and soul of Wikipedia is a community of people working to bring you unlimited access to reliable, neutral information. Please take a minute to help us keep Wikipedia growing. Thank you.

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.
However, this may not be the case for your company or your clients. You may start by looking at keyword rankings, and realize that you’re no longer ranking on the first page for ten of your core keywords. If that’s the case, you quickly discovered your issue, and your game plan should be investing in your core pages to help get them ranking again for these core keywords.
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.
