John Mueller of Google Search recently shared quite a bit on the topic of links and website ranking factors in a Google Webmasters Hangout.
Naturally gaining affirmative incoming links pointing to those blog posts will substantially help. Creating the post is only a first step, I find that marketing the post afterwards takes longer - but also is what really gets the content used.
How I understood the conversation with John Mueller about on-page linking.
When a link is no followed, Google doesn’t pass link juice.
When a link is followed but is no indexed, in this case, Google does pass page rank because they are aware of the page.
When a page is no indexed and the link is nofollow, Google essentially sees it similar to a 404 page and skips it will flag to the spiders that this page is now relevant and to re-crawl the page.
CONCLUSION: When conducting a link audit, reviewing the link risk and considering factors currently ranking sites, the need for SEOs to understand NoFollow links is still necessary. This goes beyond the scope of the content distribution networks that we've tried.
When something is this central to building your domain authority, I agree with Egol that a more hands-on approach has it benefits.
Strong social signals also help a lot: each platform is unique from Google+, to Facebook and LinkedIn for lead generation.
