Some publishers feel you may see a slight spike in your Google AdSense income in the near future. Why? As martinibuster reports in a WebmasterWorld thread, many AdWords advertisers, including myself, have received emails from Google to give the content network a try. Meaning, if the advertiser was not using the content network - now maybe they will be putting some money towards those ads and help boost up earnings for publishers.
The email explains the tools advertisers have to give them the control over the content network they once wanted, probably before they decided to opt out years ago.
There is no AdSense earnings have been lower in the past few months then they ever have. Maybe this email and the new features will help spark some life into the content network and boost publishers earnings? Or maybe not! As this WebmasterWorld thread says, the new category exclusion feature may result in many publishers noticing an even larger drop in their earnings.
Time will tell in these cases.
