Web Design Term – Hit
Generally thought to be a sort of ‘point’ gained when a single visitor visits your site. In reality, a hit is when a user requests a file from your site. As sites can be comprised of several different parts that all need to be downloaded to be displayed, a single visitor can actually create many hits to your site from a single visit.
A pageview is generally a more reliable metric when trying to measure the number of visitors to a site.
