The typical stats in the business news continue to indicate an upward trend in online advertising, but you can bet your bottom dollar at the same time more advertisers daily will find out how weak the Content Network is, and keep leaving. The money will go towards Search. Either it moves to Search, or they drop out altogether.
Complaints about revenue drops are probably the result of Google lowering pricing to keep people from leaving the Content Network.
Unless and until Google figures out it has to provide more guidance to publishers about how to make the ads convert properly, it's only recourse is to lower its prices. Google is totally incapable or adamantly refuses to help publishers beyond the most general and shortest advice possible. Their loss (and ours).
What was the best thing Google introduced to Publishers and how many years ago was that? All I can remember in the last year was zero advice and then automated useless advice.
So much for a $461.47/share stock company.
