Graig Perrine who recently launched the very impressive List Profit Secrets system just wrote an excellent piece in his blog about sales copy versus content when it comes to creating sales and generating revenue.
GoogleBowling
There is an interesting/scary thread at threadwatch about GoogleBowling.
You might want to pay attention to how fast you're getting new inbound links for your sites.
AdSense Notifier
I just installed the AdSense Notifier Firefox Extension
It's a cool little Extension that displays your AdSense stats at the bottom of your Firefox browser window.
Currently it shows your Page impressions, Clicks, Page CTR, Page eCPM & Your earnings.
It can't show Ad unit impressions instead of Page impressions, and it can't show your channel stats, but other than that it's working fine.
