citation_pdf_url resulting in 404 Not Found - DSpace 9.1

[Willian]

I'm having trouble indexing with Google Scholar. While searching for possible issues, I found that the link contained in <meta name="citation_pdf_url"...> when accessed generates a 404 not found. However, it's the same link as the item's detail page in dspace (/bitstreams/deffc152-db16-4f65-8629-283e39f8e5b2/download). The difference is that when accessed through the item page, dspace redirects to /server/api/core/bitstreams/deffc152-db16-4f65-8629-283e39f8e5b2/content and opens the document normally.

The setting in the config/crosswalks/google-metadata.properties file is the default: google.citation_pdf_url = $simple-pdf

So, does anyone know how to fix this?

Hi,

I think we'd need more information to attempt to help you.  Could you give us an example of the link that returns a 404?   I'm not understanding how the same link works from the Item's detail page but *doesn't work* if you access it directly.  Is there a chance you have Server Side Rendering disabled in some way?

You also should take a look at our Search Engine Optimization guidelines, as they provide the best advice for how to make your site accessible to Google Scholar.  Make sure to follow *all the guidelines*.
