    Hubpages says i have earned $0.20 with 498 views... Now Adsense says i have earned $0.00 with 138 views and a $.02 Page RPM(i don't know what this means)... So my question; Is adsense tracking all of my hubs? wouldn't it be closer to 498 views if it was? when i got approved i had less than 30 views using hubpages and another 30 using xomba. I undertstand hubpages but adsense just throws me for a loop.

    second question is do i have to pay to use adwords or is that free to advertise for someone else?
