We have a large digital library with thousands of papers indexed in Google Scholar. We allow Google Scholar to index our PDFs but they're blocked unless you have a subscription. So Google has full-text indexing/searching of our PDFs (great!) but then the links point just to those PDFs (boo!) instead of the more helpful abstract pages.

Does anyone know what could cause an issue like this? I am, to the best of my knowledge, following all of the guidelines laid out in their Inclusion Guidelines.

Here's some example meta data:

<meta name="citation_title" content="Sample Title"/>
<meta name="citation_author" content="LastName, FirstName"/>
<meta name="citation_publication_date" content="2012/06/26"/>
<meta name="citation_volume" content="1"/>
<meta name="citation_issue" content="1"/>
<meta name="citation_firstpage" content="10"/>
<meta name="citation_lastpage" content="20"/>
<meta name="citation_conference_title" content="Name of the Conference"/>
<meta name="citation_isbn" content="1-234567-89-X"/>
<meta name="citation_pdf_url" content="http://www.example.org/p/1234/proceeding_1234.pdf"/>
<meta name="citation_fulltext_html_url" content="http://www.example.org/f/1234/"/>
<meta name="citation_abstract_html_url" content="http://www.example.org/p/1234/"/>
<link rel="canonical" href="http://www.example.org/p/1234/" />

example.org/p/1234 is the abstract page for the article; example.org/f/1234 is the fulltext link accessible to subscribers only (and to Google Scholar). example.org/p/1234/proceeding_1234.pdf is the fulltext PDF link.

That canonical URL you have could be causing the issue. That canonical should not be on the abstract URLs or else Google will use it instead for its indexes.

Also ensure that robots.txt is not blocking your citation_fulltext_html_url path or citation_abstract_html_url path.

Minor, and probably not an issue but you have no space after the quotations. Example name="citation_pdf_url"content=" I would add a spaces just to be sure to help the parser like so name="citation_pdf_url" content=".

I'm not sure I follow you. The canonical URL is the URL for the abstract page. I want Google to use it. – JordanReiter Aug 1 '12 at 15:44
Oh fiddlesticks, just realized that the links for abstract and full text are wrong in the example code. That's why you said what you did. – JordanReiter Aug 1 '12 at 15:44
The canonical tag on a page will make that url the link in the index regardless of anything else. In other words if you have canonical = /p/1234/ on the page /f/1234/ then never will f/1234 be in google index. period. Remove the canonical in your situation because you want google to handle them all seperately. You can watch a few videos on these topics at youtube.com/user/GoogleWebmasterHelp/videos?query=canonical – Anthony Hatzopoulos Aug 1 '12 at 17:32
Also Google's Maile Ohye touches on some of the negatives of the canonical tag in this rel prev/next video (not quite the same but you'll get the idea of when not to use rel canonical and how it works) youtu.be/njn8uXTWiGg – Anthony Hatzopoulos Aug 1 '12 at 17:34
I put different canonical links on each page. So when you go to /f/1234, the canonical link is /f/1234. So that shouldn't be a problem. – JordanReiter Aug 1 '12 at 20:47
