It's in my profile. In addition to the main site, my wife and I have several geographically targeted "sites within a site" that are identified in the top navigation bar (and which are a legacy of older, separate sites from our Mining Co./About.com days).
Well, it won't go down. On my site, I've been running ad-network banners (some targeted, some not) with affiliate banners for high-quality vendors who sell to my audience. I think those affiliate banners do more for credibility than anything else does, because the reader probably assumes they're paid ads rather than defaults that I'm running to fill up unsold inventory. Still, the Google ads certainly shouldn't hurt credibility, and--like affiliate banners--they have the advantage of being related to the site's topic, which is always a plus.
I disagree strongly. After publishing Google AdSense banners on a portion of my site last night, I'm seeing a 0.9% clickthrough rate with an effective CPM of $3.33. That's a better clickthrough rate than I've seen with targeted affiliate banners and a better CPM than I've received from standard banners at FastClick or Tribal Fusion. (There's no telling if those figures will hold, of course, but logic would suggest that highly targeted text ads should do better than the run-of-network banners that most ad networks are serving these days.)
I just got an e-mail from another member who wanted to know what I meant by "effective CPM." I should have made myself clearer:
By "effective CPM," I'm referring to my net revenue per 1,000 AdSense banner impressions--not the gross CPM that an ad network might quote on its site.
BTW, I checked my AdSense report again a moment ago, and my effective CPM is now up to $4.01. That's the equivalent of a gross CPM of $8.02 on a banner-ad network that splits revenues 50/50 with the Webmaster.
