Does adsense count page impression's if i recall awhile ago they used to so far i have 180 impression's (Just got verified today) and I haven't earned anything.
Yes adsense counts impressions I think for 1,000 impressions USD 0.08 and more over eCPM+Click+impression is required to earn money from adsense
What? Do they count impressions? They track everything. Sign up for Google Analytic s and see where your visitors are coming from.
Yes, google pay for CPM but many people just ignore it because the CPM is too less compare to CPC. Google pay only about 2~3cents per 1000 impression depend on the niche. So, you gain nothing for 180 impressions is normal since it can be only $0.004
