The same rules apply to them I guess. If you want to run a serious online advertising campaign you can not overlook AdWords.
They probably slip google a couple of million to boost their pr up a bit Couldn't google just exclude all msn sites until microsoft pay up $2.7 billion?
As big as Google is...I think it would be a bad move to make the now sleeping M1cro$oft giant wake up and take action...let MSN waste their money
I've seen a few different MSN ads on G. I'm guessing that once mysite on Search Engines is complete, I'll see msn ads via GoogleAds as well.
