Hi A long time ago i read that it is possible to make adsense show only ads that pays more than an amount you choose like for example $0.25 Is it true and how can i do it?
There's no direct way of doing this. The only thing you can do is determine the obviously low-paying ads that get displayed on your site a lot and exclude those ads (there's a feature for this on the Adsense admin panel). However, if the niche you're in generally attracts low-paying ads then doing the above doesn't help you much either.
Agree with the poster above. This option isn't possible, unfortunately . If you want to earn big money from Adsense, create websites in big money niches (insurance, health etc.) and don't get into the cheap niches (proxies, pictures etc.) - Aquarezz
Both the posters above have completely nailed it. I tried doing that some time back, and found that my earnings actually decreased. Only reason I was able to deduce was that if I disable those ads, then Google starts showing other ads which might not be completely relevant and get a lower CTR. So, now I let Google decide what works best.
