This has happened to me in the past, and it's happening again. One of my sites is reporting way more ad impressions than it should. The site has had 16 visitors today, and only 30 pageviews. Yet Adsense is saying the impressions are at 199 for that channel, and there's only one ad block on the site!!! When this happened in the past, it even went up to like 800 in a day... Anyone else experiencing this?
