Here's the thing: The kinds of ads you don't mind are the same kinds of ads that perform the worst for advertisers. The CPMs will probably reflect this.
I don't know how they perform, but I assume their successful because companies keep advertising there. I don't mind these particular ads because they're high quality, not obnoxious, and relevant to me. I never click through ads on most sites, but I actually do click through these because I'm interested in the product. It's ideal advertising to me.
