1. What Niches to Chose when Creating Plain Adsense Sites
Personally I prefer to create information sites and educational sites when I plan to just add Adsense. Another good niche is to target audience that want to save money, have found this one to be really good.
A great place to look and get ideas are flippa.com. Don`t steel the exact same topic or sub niche but you can get great ideas of sites that makes money with Adsense. I just checked Flippa and came up with these niches:
insurance
game sites
student loan
guitar lessons
persona finance
car stats, car reports
typing
vitamin
dracula (this one is interesting :)
foreclosure
These all make $100 + monthly with Adsense.
As always you want to create good quality content that help the reader out in some way.
Next: Keywords - Should you go for High CPC or Low CPC?
I've found out, for me, anyway, sites built around: how to kind of keywords get me more clicks. My click through rates on my best adsense site based on late buying cycle stages has a click through rate of 3-4%. My best one built on keywords people use in the earlier stages of they buying cycle gets me 9-11%, one month it got me 5% (which is still higher than 4).
Nice one, Veronica.
