At the DLF Forum in 2010 we gave a general presentation about search engine optimization for digital repositories. In that presentation we revealed some new and surprising information about Google Scholar harvesting requirements, and how they affect institutional repositories’ visibility in the GS index. We learned, for instance, that the Webmaster Inclusion Guidelines for Google Scholar cautions us to “use Dublin Core only as a last resort” for metadata tags. One reason for instruction this is that Dublin Core cannot represent publication citation information very well. We have also learned that getting indexed in Google Scholar results in higher ranking for that same item in Google’s main index. Working with OCLC, we have continued to research SEO practices for Google Scholar as well as for the main Google index, and that research has resulted in a book contract with Neal-Schumann. We also gave a similar presentation at CNI last spring: http://content.lib.utah.edu/u?/ir-main,60502. In this year’s research update we offer a solid set of practices that can be applied broadly to institutional repositories to improve the percentage of items that are indexed by Google Scholar.
