I have niche pages targeting small KW ... more or less typical Microniche pages. I ranked them and i get the traffic related to the search volume for this Kos The amount of clicks on adsense are ok the ads displayed are related - its high competition - but they they are not paying much ..... far far less as the KW tool says. If G KW tool says 1$ ... i make maybe 0,10-0,15 cent a click in reality. So in my opinion that no enough to keep a page like that up. you always have a little work and they make less than 20$ a month if you arg KW with 1500. I even played around with ads displayed ect .... that was not a big result. and the pages are established .. i know on the beginning adsense is optimizing for your page. so my question are you gearing paid what the KW tool says ?
