Do Backlinks to a PDF help with overall authority/link juice for the rest of the domain?

[MattAaron]

We are working on a website that has some high-quality industry articles available on their website.

For each article, there is an abstract with a link to the PDF which is hosted on the domain.

We have found in Analytics that a lot of sites link directly to the PDF and not the webpage that has the abstract of the article.

Can we get any benefit from a direct PDF link? Or do we need to modify our strategy?

You can/need to build links from within the domain to thePDF report you want to share also. Links within the PFD file will also help for people who share the file via email, and not within the site. This will bring people back to your domain.
