Facts that you should know:
A proprietary author ID for Scopus: Scopus Author ID is an author ID that Scopus automatically assigns to each author in its database to group publications of the same author together. For the set of documents grouped under the profile of an author ID, Scopus provides bibliometric information such as citation counts, h-index, and h-graph via its citation overview function. Scopus Author ID is now ORCID compliant.
Multiple Scopus author IDs for the same author and possible mismatch: Because of author name ambiguity issues and other reasons such as prior affiliations, the automatic matching algorithm of Scopus may generate another new ID for the same author when a new paper is included in the database. Multiple author IDs lead to identity splitting and different clusters of publications. In some cases a paper can even be mistakenly mapped to a wrong author. All these adversely affect the accuracy of an author’s bibliometric data and the discoverability of an author’s works.
Things that you should do:
Review and refine your Scopus profile from time to time: To take full advantage of the Scopus Author ID to identify all your works in Scopus and to ensure accuracy of your bibliometric data, it is essential that multiple IDs (if any) are merged and misattributed articles (if any) are corrected. Please review your Scopus author profile from time to time and report errors to Scopus via its author feedback wizard.
Integrate your Scopus Author ID with ORCID: Scopus Author ID is a proprietary author ID used by Scopus only. Integrating your ORCID iD with your Scopus Author ID enables Scopus to recognize you through the ORCID iD that you have used to distinguish yourself when you submit your papers to the publishers that have also integrated ORCID in their workflow (see the full list of integrators). Scopus can then correctly assign your papers under your existing Scopus Author Profile. The integration will also enable the searching of your work in Scopus with your ORCID iD.
Note: Scopus is the data source for university ranking agencies such as QS World University Rankings, Times Higher Education (THE) World University Rankings and US World News & World Report's Best Arab Region Universities Rankings.
