According to Ahrefs LinkedIn collaborative articles are getting about 500k of organic traffic per month. So if you play your cards well, those articles can give you a lot of exposure. The first step to leveraging collaborative articles is to collect data.
Features
Get a list of collaborative articles for a set of topic
Get a list of contributions for a set of articles.
If you have idea for new features let me know. The still is still early stage.
Use cases
Once you have identified relevant articles you can start answering them in order to build thought leadership on Linkedin.
However, there are plenty of other use cases for those data (I will be publishing detailed tutorials for each of them):
Identify Linkedin Influencers
Create a content plan from Linkedin
Create a blog post from collab articles.
