That sounds kinda boring... - So be interesting!
Yep - a lot of those topics are about as interesting as going to the dentist - in fact "Dental Plans" is one of those high paying keywords!
What the world needs is NOT some lame website about some topic the website owner has no interest in.
So create websites or blogs about things that you're interested in.
But how do you make money from that?
Remember I said there were 2 things that determine how much money you'll make? The second thing was how much traffic you get.
Get lots of traffic and you'll get more clicks on your ads.
