Web Survey Bibliography
Impact of measurement periods on website rankings is investigated using the data collected by a user-centric method. Their impact on the estimation of website traffic is also investigated. The findings indicate that site reach increases by approximately 71% from one day to one week and one week to four weeks, and site frequency increases by 55% from one week to one month. Site rankings are found affected not by the length of measurement periods but by the sorting criterion.
