I have a few sites (in my signature below) that have AdSense ads on them. I also have an AdWords account for a different purpose and while in that account recently I used the placement tool and searched for the URLs of my sites to see if I could find them. I got an error messsage saying that they are not able to be targeted via Google placements. Why is that? I thought that if you were an AdSense publisher you were automatically listed as a targetable placement. I am about to receive my first check from Google this month. Does that have anything to do with not yet being listed? Thanks for any info!
