… John, seems to me Facebook’s @CrowdTangle is a possible solution that is already in place to detect trending content and track influence across various platforms. As they state they already cover:
- Facebook: More than 820K Facebook Pages. This includes all Facebook Pages with more than 125K fans (new Pages are added automatically via an API), as well as all Verified Facebook Pages.
- Instagram: More than 280K public Instagram accounts. This includes all verified Instagram accounts. And if an account in our system *tags* another account with more than 50K fans in a caption, that account will be automatically added to our system via an API.
- Twitter: More than 490K public Twitter accounts. This includes all verified accounts (as of March 2017).
- Reddit: More than 10K of the most active sub-reddits. Built and maintained in partnership with Reddit.
