The Scopus Author Profile allows the database to group and track publications by a specific author, attempting to group publications under the correct author (even if multiple authors have similar names). Authors can update/correct their profile. This has similar features to other author metric / citation tracking cites ( Researcher ID / Web of Science, ORCID, Research Gate, Google Scholar).
The Scopus Author Profile creates a specific Scopus ID for each author. This is one of several sites which have similar features (including tracking new citations and/or creating metrics of authors' research impact/productivity).
