Hubpages pays you on the impressions and so the stream of earnings will be quick.
Though Google Adsense pays money both on “clicks” (CPC) and on “impressions” (CPM) - it depends on the mix of CPC ads and CPM ads you get. By default what we get is CPC ads and the CPM ads is displayed based on the Advertiser choice only.
So unless somebody "clicks" on the Google Ads that is displayed, it is not possible to get earnings through Adsense.
Nobody has control over it and it is purely viewer's prerogative and it depends on various factors.
To get more clicks you should get more organic traffic (rather than referral sites) - to get more organic traffic, you should have good SEO optimized articles - so ultimately it boils down to good quality content which users should be able to find out while searching.
