Just like any website page, you want to make sure that the PDF is connected with your website pages.
This will prevent the file from becoming an “orphaned page,” and provides more context to how this file is related to other site content.
Links signals to Google that the PDF content is relevant, and should be indexed.
Additionally, if you’re not doing this, then the only way anyone could access your PDF is if they find it through search engines, so you want to make sure that users that find your website a different way can still view it.
4. Include links in the PDF to relevant content
Similar to the tip above, including links in the PDF can help Google understand the relevancy your PDF has to other web pages.
By including internal links back to your website, you’re also making sure that the traffic you’re earning from this PDF has a pathway to learn more about your business, products, or services.
