Understanding PDF metadata
Title, author, keywords: what a PDF's metadata actually contains and why it matters.
What is metadata?
It's information invisible when reading the document but stored in the file: title, author, creation date, software used, and sometimes keywords.
Why it matters for SEO
Search engines use the document title as a relevance signal, and it can even show up directly in search results.
What about privacy?
Metadata can reveal the real author of a document or the software used to create it; worth checking before sharing a sensitive file.
FAQ
