There is a thread over at that other place that makes the case - "Faster page rendering equals more Adsense money" Some webmasters seem to agree. Some contend that the slowest loading portions of their pages are NOT due to their servers, but are due to 1. Slow-loading Adsense ads, and 2. Even slower-loading Google Analytics. Some say that the Google servers are slower than they were in the past. I have noticed slow-loading ads a few times myself, reducing the opportunity for clicks. Would it be a prudent test to temporarily remove Google Analytics from a few high-volume, high-paying pages to see if revenue increases? We can't remove the ads (ha-ha), but we can try removing Analytics. Has anyone experimented with this?
that seems to be the case for one of my blog as well. the entire pages loads instantly but the sidebard where adsense code is loads a second later
