does the positioning on my site affect it, or how many people click on the banners, or page impressions?
i ask this as for the last 2 days it's been at 0.00. i understand that it goes up and down, but is this due to something i have not done right .. or is this normal?
I'm sorry if i have missed a blatent explination for this somewhere else on these forums.
eCPM is easy to calculate: Just take total earnings for a day, week, year, or whatever and divide by the number of 1,000-impression blocks. For example, if you have $5,000 in earnings and 1,000,000 impressions:
$5,000 divided by 1,000 = $5 eCPM
If you have $1,200 in earnings and 780,633 impressions:
$1,200 divided by 768.633 = $1.56 eCPM
eCPM is a useful metric because it lets you compare AdSense with other sources of income. It also gives you an overall view of performance trends. Let's say, for example, that you've got a site on ice fishing. In winter, you earn $5,000 a month from AdSense, but then summer comes and your AdSense revenue drops to $1,000 a month. If you were to judge AdSense's performance by total revenues alone, you might think that AdSense was performing poorly, when in fact revenues are down only because traffic drops in the summer on your ice-fishing site. By comparing month-to-month eCPM instead of total revenues, you get a more accurate picture of AdSense performance.

To get eCPM of 0 mean that you either have 0 earnings or 0 impressions (0 numerator or 0 denominator, although last is technically null). This definitely is not good - it basically means that your site is not earning anything from your visitors.
There are lots of ways you can improve it - start with Adsense tips on your Google page. Study the heatmap and the ideal ad positioning.
