Visits are an important metric but attention should be paid to exactly what constitutes a unique ‘visit’. o When a user, identified by an IP Address visits your web page for the first time it is recorded as a unique visit – only page requests are counted as visits. All subsequent page requests from that IP address are treated as being part of the same visit making this metric more accurate in counting individual users of your website – as long as they all occur within a set time window of each other , usually 30 minutes. What this means is that a user could visit your website, click and view 5 pages and it would still count as one visitor if the time between clicks was less than the timeout period. If the same individual returned to your website say 2 hours later then it would count as two visits.
Visits are one of the most reliable Webalizer indicators of real person activity as they only record complete page requests whereas sites that link to your files e.g. images would generate a misleading visitor statistic each time the image is requested for example.
