AdSense have announced a couple of changes. One is that they’ve replaced ‘site targeting’ with ‘placement targeting’. Now advertisers can target their ads to specific ad units on your blog (depending upon how you’ve set your channels up).
The second change is that they’re now allowing advertisers to target sites with CPC ads (cost per click) rather than just CPM ads (cost per thousand impressions).
I’m not really sure how this will impact publishers. I did hear a couple of other things from AdSense that concerned me a little though – I’m not at liberty to reveal them yet – but hopefully can in the coming week or two.
