One measure of the success of the Armagh web-site is the annual number of distinct e-Visitors (DeVs), in fact the number of distinct hosts served by the Observatory's web-site. This is a lower limit to the number of e-Visitors, owing to caching by big servers and sharing or repeat visits from the same IP number. A second measure of success is the number of `hits', defined as the number of successful page requests. This is typically 5-20 times greater than the DeV statistic, but depends not just on a user accessing a web-page but the way in which the web-page has been configured, for example whether as a single file or to include graphics and other links as well. A third, and arguably the most useful measure of the `value' of a web-site, is the amount of data transferred from the site, or `exported', to external users. A single page request or distinct e-Visit simply demonstrates that someone looked at the Observatory web-site, but does not indicate how long they stayed or what they thought of the information provided. However, the amount of data exported provides an indication of the value of the web-site as a source of information.
For the Observatory's three principal web-sites (star, climate and arpc65), the detailed breakdown of these figures for 2004 is shown in Table 3 (see http://star.arm.ac.uk/stats.html). The recent trend in the adopted number of distinct e-Visitors is shown in Table 4.
