I am not running those Adsense micro-niche sites, but a few general purpose guides, tutorial sites with around 7k unique visitors every day among 3 sites. So, 7k unique visitors are converting into $0.82/day in ad revenue on Adsense which is very low. My last 7 days earning is $5.42 whereas last 28 days, it's $17.31 I am running 3 days limit per page with a banner ad on header and footer and one ad between content. I have also opted for Page level ads for mobile which is converting the worst 77k total impressions on page level ads and Estimated earnings $0.21 total which is pathetic. Can someone experienced in milking revenue from ads give me some tips?
