Search engines (especially Google) are unpredictable. No matter how adept you are at using the AdWords keyword planner or how targeted your SEO strategy is, you can never be completely sure which of your blog posts or even your landing pages will perform the best — and which keywords they’ll rank for when they do. You’ve got to hit publish, then wait to see how the results shake out over time (and it can take months for a post to gain, or not gain, the traction you’re looking for).
Well as noted in the post it is not just above the links that was only one key part of a wider strategy. This website in question has deep levels of content. So it is not just about a blog section, they have numerous high quality content sections we have developed over time. It would not be advisable ever to attack competitors sites with low quality links.
Regarding Link Detox, links it diagnoses as Toxic are generally fine as they're either not indexed by Google or have malware/viruses/etc., but I recommend a manual review of any diagnosed as Suspicious. I used it recently to get started cleaning up our backlinks and some legit sites and blogs were under Suspicious simply because they didn't have many links pointing to them.
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?
Mobile traffic: In the Groupon experiment mentioned above, Groupon found that both browser and device matter in web analytics’ ability to track organic traffic. Although desktops using common browsers saw a smaller impact from the test (10-20 percent), mobile devices saw a 50 percent drop in direct traffic when the site was de-indexed. In short, as mobile users grow, we are likely to see direct traffic rise even more from organic search traffic.
