Over the last 12 months with Google upping the ante on web spam in particular related to link building, there has been a general shift from the use of Free directories, article marketing to blogger out reach, PR and of course content marketing. Some great tools have been produced to help your efforts, whether it be to think of content suggestions or find ideas which have worked well.
Last year Yousaf Sekander launched his https://socialcrawlytics.com/ tool, which was basically a web software that you could put any site in and see which pages were shared the most and you could view number of tweets, Facebook shares etc. This was a great tool to look at what content has done well, not only on your own site but competitors or influential blogs etc.
