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.
At our agency, we work with sites of varying sizes, from very large to quite small, and recently, we have noticed a trend at the enterprise level. These sites aren’t relying as much on Google for traffic any more. Not only are they not relying on Google traffic, but also, the sites are getting less than 10 percent (or slightly more) of their organic traffic from the search giant.
