1. When do impressions add to your account dollar total? I've crossed into the 1000 impressions range a few times now but have yet to see anything added to my dollar total. 2. Should all ads on a given "Content" ad append to the impression count or is it based on how advertisers choose to pay for ads (either per X impressions or per clicks). In other words, if an advertiser is only choosing to pay for clicks and they appear on your site, do they then not add to the impression count? 3. If I have 3 content ads on my screen (i.e. top, left, right) and each has 4 advertisers on them, should the number of impressions for a given "page served" be 3X4=12, or is the forumula more involved than that. It doesn't appear to be as simple as the simple math forumla. Thanks in advance for any replies. Kevin
