What´s a Google Scholar Profile?

You will then be asked for your name, affiliation, etc. Next, Google Scholar will automatically suggest publications to add to your profile. Select the ones that are yours to add to your profile. Add your research interests as keywords, which can then be used to search on by people looking for other researchers in a field.
What´s it used for?
