We all do peer review of manuscripts as part of our job. But we don't get any recognition for the quantity and quality of reviews we provide.
Publons is an interesting initiative that is trying to address this issue.
The simple idea is that your profile on Publons gives you (and others) a quick verified overview of how many reviews you have provided and for which journals you have acted as a reviewer. You can also link your publons profile to your ORCID profile so that you have this information in one place.
