Other content should then link into that cornerstone content. This creates internal links between your blog posts. Make sure that you always link back to your cornerstone content, to tell the search engines of the importance of that content. Internal linking this way optimizes your SEO. By optimizing your SEO, you increase the organic search traffic to your blog.
To do this, I often align the launch of my content with a couple of guest posts on relevant websites to drive a load of relevant traffic to it, as well as some relevant links. This has a knock-on effect toward the organic amplification of the content and means that you at least have something to show for the content (in terms of ROI) if it doesn't do as well as you expect organically.
