There are quite a few professors at my school that do not have a Google Scholar profile at all. I may search them in Google Scholar's search engine and hope their most recent papers come up, but I am not able to access their h-index or any of the other metrics supplied by Google Scholar. If I search a paper by them, I can see it listed, but the author's name is not underlined and it doesn't seem as though they have a profile.
Microsoft Academic seems to create "profiles" for people and then allow them to claim it, letting others at least view data about the person in question even if they have not created an account. Is there any way to do this with Google Scholar?
