Site Targetting Problems

[akreider]

My site-targetted ads have a CPM of about 1/20th of my regular CPM -- which isn't anything special - I get your typical CPM rate.

On the other hand, the proportion of site-targetting is extremely low (I've only had 4000 site-targetted impressions).

Will my site-targetting CPM rate increase? Or why is Google letting people do site-targetting with such pathetically low CPMs? If I disable site-targetting would it have any negative impacts?

What pages are the site-targeted ads showing up on? Maybe only on pages that have extremely low eCPMs. If that's true you are actually benefiting, as they are earning you a few pennies instead of nothing.

More detailed analysis needed.
