If you're in a low paying niche like me (0.1-0.5 CPC on adsense), then I see no point in using adsense at all. CTR is usually about 1-5% Let's say average CPC is $0.5 so to get $20, you'll need 40 clicks. And lets say CTR is 2.5%, that means every 1000 visitors you'll get 25 clicks. To make $20, you'll need 15 more clicks which is equivalent of 600 visitors. Therefore, total visitors for $20 is 1,600 visitors. Now surely, if you had a clickbank ad / banner instead, you should be easily able to make AT LEAST 1 sale from that 1,600 visitors right? That's a conversion rate of 0.0625% which is awfully low. Realistically, the conversion rate should be like 0.3-5% (depending on the niche) so that means clickbank would be a much better way to monetize your site than with adsense. Also adsense likes to ban people a lot for not even breaking the rules so I'd say Click bank would be a much better alternative.
