MFA and Filter Adsense to Get high Ads

MFA = Made for Adsense sites.
They bid extremely low on adwords and their ads you get on your site pay low (like your 0.05).
Filtering some MFA sites can get better results for you.
Have google adsense preview tool and preview the ads that are appearing in US and UK,
there's a "Show Ad URL" option,
check the url to decide if it's an MFA site and filter it in your adsense acount.
It helped me a lot. i now have 1-4$ per click ads on my page.
