I haven't been using adsense for a long time so I am sorry if this is a dumb question. Today I noticed that the impressions reported on Adsense for my site are about half the number reported on google analytics and site meter. Does Adsense take a while to update stats during the day, or is there another problem or issue I should be aware of?
My AWstats tells me I get like 3k uniques a day yet adsense shows only like 30-70 impressions a day(proxy)
