With the increasing creation and use of institutional repositories (IRs), Search Engine Optimization (SEO) is necessary to draw users to digital collections. Arlitsch and OBrien provide useful information in their book, Improving the Visibility and Use of Digital Repositories through SEO, part of the LITA Guide series.

Google Analytics and Webmaster Tools are just a few of the services available. It is also important for them to be aware that every decision made in implementing the tools will affect the organization's ability to identify problems and may also have an impact on reporting factors to stakeholders. Arlitsch and OBrien discuss search en-gines' free webmaster tools, which aid in analyzing IR indexing, and identify where crawlers run into problems. There are additional tools that assist in gathering other site statistics including visitor counts, country …
