A data collection system collects statistics related to each visit to each web-page within a web-site. In addition to collecting path information related to traversals to and from each web-page, the system collects information regarding the particular session, such as the visitor's connection speed, the time required to download the web-page to the visitor's system, the duration of time that the visitor spent at the page, whether the user clicked the 'back' button to leave the site, and so on. The data reporting system presents statistics based on the collected data in an easy-to-use and easy-to-understand form that is customizable by the user. By collecting and reporting performance factors related to each web-page, or sets of web-pages within a web-site, marketers and webmasters can address any perceived deficiencies and/or can optimize the performance of select pages to achieve specific marketing objectives. To optimize performance and minimize storage requirements, the data collection system uses a two-stage storage architecture. Data is collected in one or more registers in a sequential fashion, and transferred to a database periodically.
