Impressions are how most Web advertising is sold and the cost is </p><p>quoted in terms of the cost per thousand impressions (CPM). </p><p><BR><BR> </p><p>Hit: A hit is the sending of a single file (HTMLfile, an </p><p>image, an audio file, or other file type). The number of hits from a </p><p>site is not a good indication of actual number of visitors, but for the </p><p>website space provider, however, hits can indicate traggic flow. </p><p><BR><BR> </p><p>Source: http://www.whatis.com/adterms/htm. </p><p><BR><BR> </p>
