If you have been making money using Google AdSense for more than a few months chances are really good that you have read or benefited from knowledge shared by Jennifer Slegg. JenSense, her indepth blog on monetizing your website, is without peer - and that includes Inside AdSense!
AdSense has been slow to share a lot of information about optimizing your income - many times posting suggestions that have been given by many sources beforehand.
Their post yesterday about revenue fluctuations, while somewhat informative - when not trying to suggest they could be due to impression drop off - comes in response to the numerous articles and forum discussions about dropping AdSense income.
Jen I look forward to reading your entries this month.
