I don't normally use site targeted ad's but I've just set this up for a client and I wondered what the average CPM for a site-targeted campaign is? It'll obviously be different for every type of website but I just want to get a rough idea so that I don't set the pricing too high in order to start getting some impressions.
There's no average, at least not one that anyone outside of Google would have access to. It starts at $0.25 and goes up from there. See; http://adwords.google.com/support/bin/answer.py?answer=18267 & http://adwords.google.com/support/bin/answer.py?answer=19649
