I'm still about $999,998.21 shy of a million bucks.
After having Ad Sense on my blog for about 6 months, I only accrued about a buck and some change in ad revenue.
It could be because I don't have enough readers.
Or it could be that all my readers are too
It's probably because Ad Sense notes key words on your blog and posts ads that seem to be related to your topics. Consequently, the only ads I seemed to attract were ads for Weight Watchers (who I hate) and Jillian Michaels (who I also hate). Telling my readers how much I hate these products is not the most effective way to earn ad revenue.
Know who I love? V-Fit.
If you want to spend money to get fit, don't spend it at Weight-Fucking-Watchers or Jillian-Horseface-Michaels. Spend it at V-Fit. Skype workouts are available. And really, really, hard. And really, really effective.
I won't earn any ad revenue, but at least I know that all of my 81 wonderful readers will have access to the best.
