There are different types of Researcher IDs - platform neutral & platform specific:
An ORCID is a unique researcher identifier, used worldwide, that you keep throughout your life and retain even if you move institution or change name.
The ORCID website also provides more information on building your ORCID record & importing existing publications. You can also link your ORCID to other identifiers, for example Scopus Author IDs.
To be eligible for inclusion in Google Scholar search results, you need to have a Google Scholar profile which is public and needs to have a verified email address at your university. Your Scholar profile links to a Google account so you must sign in or create one first.
Google provide useful guidance on setting up your Scholar profile and adding articles.
Scopus profiles are automatically created when two or more articles are linked to one profile. You can use the Scopus Author Feedback Wizard to review and manage your Scopus profile.
Web of Science have replaced their ResearcherIDs with Publons profiles. You can use Publons to track your publications, citation metrics, peer reviews and journal editing work in a single profile. You can also link your Publons account to your ORCID account.
If you already have a ResearcherID or an account with Publons, EndNote or Web of Science, you can log in with your credentials for that service to start using Publons:
If you haven't used these services, you will need to register & set up your Publons profile:
You can add your papers to your account from your private dashboard. Publons provide some useful guidance.
Once you have added publications, a Metrics tab will be accessible on your profile showing your impact over time, publication metrics and review metrics.
Publons will automatically assign a Web of Science ResearcherID to any profile with a Web of Science Core Collection-indexed publications that do not yet have a ResearcherID.
