I just launched a new site and it is getting over 13,000 impressions a day according to adsense. But according to google anlitics I am geting around 50 impressions a day. I believe the later. Anyone seeing anything like this?
You can customize Analytics to ignore impressions from your IP, but you cannot do that with AdSense. That may explain some of the difference, but 13,000 impressions? I don't think you can refresh THAT many times...
Keep in mind that if you have 3 adsense blocks on your page each block will count as an impression when someone loads your page.
