The keyword-targeted ads that you're used to seeing on your pages will now be joined by a new type of site-targeted advertisement. Site-targeted ads allow advertisers to select the specific sites they feel are most appropriate to their campaign, and to run their ads only on those sites.
With site-targeted advertising, advertisers set a maximum CPM bid - that is, the price they are willing to pay for every thousand impressions – and pay on a per-impression basis. This means that, unlike pay-per-click ads, you'll earn revenue each time a CPM ad is displayed on your site.
There you go. There is the answer as to what is happening.
Back to banner days, CPM's...
And I guess we'll have to make sure the pages look pretty from now on also...never mind text only rich content pages. In the eyes of the advertisers they probalby won't cut the mustard!
One thing is for sure, I'm not going to invest hundreds of hours to embellish my pages for adsense and try to "guess" what advertisers are looking for.
I also wonder if as a small adword advertiser I'll also be able to "choose" where I want my content ads to appear...but I've got a funny feeling that this "privilege" will be kept for minimum $10 000 a month spend advertisers or something, that's my prediction...
