PDF SEO
PDF files can be indexed by Google, which reads their text, metadata (Title, Author), and internal links. A well-structured PDF with a descriptive document title, selectable text, and outbound links can rank for precise documentary queries.
In practice
Common mistakes include scanned PDFs (unreadable images), generic document titles ('document1'), and no return links to the site. For a consulting firm, a white paper PDF titled with the target query, hosted on its own domain with a dedicated landing page, can rank durably on terms like 'SME tax audit guide PDF'. Always verify text accessibility with pdftotext before publishing.
