I'm using woopra and google analytics on one site. Both are reporting 100 unique visits to one site. Browsers - 70% Firefox, 10% chrome, 15% IE and remaining are others. My adsense stats are showing only 20-30 visits for this website. Even though analytics and other stat programs are showing more visits, adsense counting only 20 or so impressions out of it.
What seems to be the problem here ?
