Some little answers.
Page Impression
We count a page impression when our AdSense JavaScript is actually executed by a user's browser and ads are displayed. This is generally the equivalent to a page view, but as described in Why do I detect a different number of page impressions than what shows in my reports?, there are instances that wouldn't execute the ad code and that would cause a discrepancy between the page impressions you register and the page impressions that appear in your AdSense account.
Note that page impressions differ from ad unit impressions. If multiple ad units are present on a page, multiple ad unit impressions will be logged for that page view, but only a single page impression will appear in your reports.
For example, a user viewing a page with 3 ad units and 1 link unit will log 4 ad unit impressions, but only 1 page impression.
------------------------------------
Clickthrough rate (CTR)
The number of ad clicks divided by the number of impressions for the page of ads that appears when a link unit is clicked.
-------------------------------------
Effective CPM
From a publisher's perspective, the effective cost-per-thousand impressions (eCPM) is a useful way to compare revenue across different channels and advertising programs. It is calculated by dividing total earnings by the number of impressions in thousands. For example, if a publisher earned $180 from 45,000 impressions, the eCPM would equal $180/45, or $4.00. However, please keep in mind that eCPM is a reporting feature that does not represent the actual amount paid to a publisher.
If you need any more information about this, feel free to ask.
