I just implementet adsense auto ads, but I just made a normal advertisement, inserted the code insted of a picture and selected it to be displayed "just below the page header" and for guest, as for our site too over 90% of traffic is unregistered users. the ads now show only on top of the page, and nowhere else. and the other display choices doesnt work either. If I select all other options for showing in forums, between topics and whatever nothing happens. adsense console says 14000 impressions first day and 68 clicks. No idea how much thats going to amount to in real money. It says estimated 8 USD.
So this way of doing it sort of works.
edit: correction, I just spotted an ad in the middle of a blog posting.
