How can I put my publications into Scopus?
Scopus uses its own sources for publications in the form of publisher provided content. Their selection procedure is explained here: https://www.elsevier.com/solutions/scopus/content/content-policy-and-selection

There is no procedure to add individual documents to Scopus that I could find on their help pages. You should also be aware that it can take several weeks for a published paper to end up in Scopus. Some publishers (smaller publishers typically or new open-access publishers), conferences, technical reports might never make it to Scopus though.

On a related note, the citation count will probably lag behind Google Scholar.
