Looking at some reports, I found that a client's site has PDFs that are ranking well for niche terms and getting some traffic. What can I do to get more out of them from a marketing standpoint? The obvious issue is that a PDF doesn't have the interactivity of a site visit, where we have analytics and CTAs. Someone has to follow a link back from the PDF to the site for us to even register a visit, let alone try to get their email or have them otherwise convert. My first guess is to make landing page summaries of the PDF content that link to the PDF, and canonical the PDF to the respective landing page. Has anyone tried this, or done something else that they would recommend again in this situation?
