I have a stock blog that I have written for two years. It has over 350 posts all written by me. I earn about $5-$10 a day in adsense. There are about 10,000 -15,000 page views every month according to google. I believe stocks and finance should be in a high paying niche. How come I can't get close to that $100 a day mark? Wow though to your success.
I've tried adwords already. The problem is every word I find is a minimum of .20 or so to get an ad in. I did some keyword research to see how much the CPC is for the keywords I use. The clicks on my site I guess are like .30 or so each but my CTR is around 2-3%. Every month I write between 15-20 articles. My adsense revenue is between $100-$150 a month. As a test, I setup a $5 a day budget in adsense and spent .10 per click. At the end of a month I spent like $40-$50, but my adsense revenue still stayed the same. My blog is at www.rawgreed.com. How someone got to $100 a day after two months amazes me. I think I've been doing something wrong for the last two years.
