Thanks, I had not tried Ad Planner before, so I just logged in as AdWords user and found that my AdSense sites are not in the database ("Ad planner could not find GDN data... ").
If the number of AdSense ad-servings vary for my channels between 1000 and 2000 a week, while as Kobayashi pointed out his channels require 1000 servings p/day to appear, I presume that without at least that number of ad-servings, a channel and URL cannot be found in AdWords and Ad Planner. As such, I will remove my sites from AdSense. There's simply is no need for me to clutter my sites with ads just to earn €0.0.. something p/click, when I can easily sell a banner placement to a single customer directly and who will pay more than the total AdSense earnings in the last 1½ years (I only recently topped my minimum €70 payout limit).
The AdSense system is surely working well for those publishers whose publications can be found and specifically picked by advertisers, but for those whom this is not working, the AdSense system is providing a half-service only, both to advertisers and publishers, by missing a vital part of any intermediate advertising media placement service.
