How to Define Searching Sessions on Web Search Engines
We investigate three methods for defining a session on Web search engines. We examine 2,465,145 interactions from 534,507 Web searchers.

Research results shows that defining sessions by query reformulation along with Internet Protocol address and cookie, provides the best measure, resulting in an 82% increase in the number of sessions. Regardless of the method, mean session length was fewer than three queries and the mean session duration was less than 30 minutes. Implications are that unique sessions may be a better indicator than the common industry metric of unique visitors for measuring search traffic. Results of this research may lead to tools to better support Web searching. Categories and Subject Descriptors H.3.3 [1] Information Search and...
