Welcome to the Q&A Forum

We have a website that has links to documents related to various sectors. But the challenge is we do not have the documents on the website itself and they are linked to our document repository that has been blocked to google. We have put nofollow and noindex to the repository. Since Google can not read those documents, it has resulted in an impact in our SEO ranking. What would be the best way to make Google crawl the PDF documents in the repository at the same time make it invisible the "repo" not appear in the search engines.  Would dofollow and noindex sequence work ?
