问题
GA is reporting that my page load time is very high, I suspect this is because I load slow-to-load ads in an i-frame, however I am unsure if GA counts content loaded in an iframe when it calculates a "Page Load Time".
回答1:
I ran some tests and confirmed that loading external content into in iframe (from a slow source) in Chrome/Firefox does indeed increase the "Average Page Load Time" in Google Analytics.
