Hits occur each time our servers send a file. For example, if a webpage consists of an HTML file, three images, and two JavaScript files, accessing this page would result in six hits.
Visits are a count of unique IP addresses requesting pages from a web site per hour, regardless of how many requests that IP address makes. Visits generally give a more accurate representation of website traffic in terms of real users.
Due to bots, search engine crawlers, and proxy servers these numbers should not be considered completely accurate.
