The majority (70%) of site traffic comes through generic Google searches. Below is a breakdown of site traffic by entry source. The first term is the source, and the second refers to the medium. Possible media include “organic” (unpaid search), “cpc” (cost per click, i.e., paid search), “referral” (referral), and “none” (direct visits have a medium of “none”). The (direct)/(none) entry includes links that are not recognized by Google Analytics, such as bookmarks or links found in eTOCs and PaP alerts. This is the first year that an image-based search engine (Imgur) has made the list.
Since launching the mobile-optimized journal site in October 2011, there have been over 125,000 pageviews via mobile device. According to Google Analytics, iPad users accounted for the vast majority of visits. iPad users interact with the regular online journal site rather than the mobile-optimized site. Tablet and smartphone users are redirected to the mobile site.
