Zotero is designed to get metadata from abstract pages, e.g. from reference databases, but there is a way you can add metadata (bibliographic information) to the pdf:s you have in Zotero:
Right click on the pdf in your zotero library and choose "retrive metadata from pdf". The post will then automatically be enriched with metadata from google scholar. In order to make this work, pdf indexing must be activated in Zotero. Go to Edit > preferences > General and mark the relevant boxes under File handling. The system prompts users to activate the pdf indexing function the first time you try to retrieve metadata, see link below.
If this does not work, go to an abstract page for the pdf in a reference database and get the metadata from there, or add the metadata manually in zotero.
