Microsoft sees no reason to increase the offer for Yahoo. Actually, even the current offer over US$ 44,6 billion is for me not understandable high.
The AdWords Standard
Since 3 years, it happens to me at first talks with new clients again and again. We talk about a new search engine optimized website, and I am asked to compare a of prognosis of the performance of the new site against Google AdWords.
Not a single time, I heard YPN - Yahoo Publisher Network. This is since years in betatest and only available in the US.
Discussion forums of professional webmasters
Observations over discussions in professional webmaster show the following trend:
The CTR (Click Through Rate) is at Google AdSense much higher. This is attributed to more relevant ads shown on the page by Google.
YPN pays more per click. This makes the publisher happy, but not the advertiser, having to pay more for one visitor.
2007 and 2008 is a tendency in the YPN forum to remove YPN ads, because they earn less than at other ad networks.
