Measuring web traffic

Measuring web traffic

Web traffic is measured to see the popularity of web sites and individual pages or sections within a site.

Web traffic can be analysed by viewing the traffic statistics found in the web server log file, an automatically-generated list of all the pages served. A hit is generated when any file is served. The page itself is considered a file, but images are also files, thus a page with 5 images could generate 6 hits (the 5 images and the page itself). A page view is generated when a visitor requests any page within the web site – a visitor will always generate at least one page view (the main page) but could generate many more.

Tracking applications external to the web site can record traffic by inserting a small piece of HTML code in every page of the web site. Web traffic is also sometimes measured by packet sniffing and thus gaining random samples of traffic data from which to extrapolate information about web traffic as a whole across total Internet usage.

The following types of information are often collated when monitoring web traffic:

• The number of visitors.
• The average number of page views per visitor – a high number would indicate that the average visitors go deep inside the site, possibly because they like it or find it useful.
• Average visit duration – the total length of a user's visit. As a rule the more time they spend the more they're interested in your company and are more prone to contact.
• Average page duration – how long a page is viewed for. The more pages viewed, the better it is for your company.
• Domain classes – all levels of the IP Addressing information required to deliver Webpages and content.
• Busy times – the most popular viewing time of the site would show when would be the best time to do promotional campaigns and when would be the most ideal to perform maintenance
• Most requested pages – the most popular pages
• Most requested entry pages – the entry page is the first page viewed by a visitor and shows which are the pages most attracting visitors
• Most requested exit pages – the most requested exit pages could help find bad pages, broken links or the exit pages may have a popular external link
• Top paths – a path is the sequence of pages viewed by visitors from entry to exit, with the top paths identifying the way most customers go through the site
• Referrers; The host can track the (apparent) source of the links and determine which sites are generating the most traffic for a particular page.

Web sites like Alexa Internet produce traffic rankings and statistics based on those people who access the sites while using the Alexa toolbar. The difficulty with this is that it's not looking at the complete traffic picture for a site. Large sites usually hire the services of companies like Nielsen NetRatings [1], but their reports are available only by subscription.
