Aardvark Question – Online Advertising CPM

What’s the range of average CPM for online display ads, from low to high targeting of specific demographics?
– Rob R. M / Santa Monica, CA

The range would be from $40 for 1000 impressions on a site like Manufacturing.net up to $200/1000 impressions on high traffic, demographically targeted websites.

These are for text or image ads, the higher end of the range can include flash ads as well.
