According to a recent release Google has decided to shut down all of AdMobs web advertising capabilities, leaving thousands of affiliate advertisers in the dust. They are pushing instead their own Google Adsense for mobile web content as the preferred method of advertising on web-based mobile content.
This comes on the heels of numerous complaints from both publishers and advertisers that accounts that have been in business with AdMob for years have been suddenly shut down without notice. While AdMob had great customer service, many people have expressed that the transition to Google has resulted in the typical “no comment” customer service Google is known for: Shut something down, respond with a template response on why it happened.
This seems to be part of a long trend of Google advertising buying properties and then failing to properly integrate them and shutting them down.
