Many researchers share work and article mentions on ResearchGate and LinkedIn. Article mentions on these websites should be included in the Attention Score.
Thank you for your suggestion!
We don't currently track ResearchGate readers or downloads in Altmetric. This is because ResearchGate data is not currently available via their API in order for us to include it as a data source in the Altmetric database. We'd be happy to work with them!
Regarding Instagram, unfortunately their posts don't include links. We would need a link to a publication to pick up a post". If Instagram updates to include links in their posts we'd be happy to revisit.
