I've emailed our lecturer about the recent problems we encounter mainly about 1)which statistics,the google adwords or the google analytics, is accurate? 2)does the change in the bids register immediately or after some time?

Our lecturer Steffen replied almost immediately. Here's the email.

Hi Antony, I would post the question on GOMCHA. I experienced similar things duringmy campaigns and think there is a certain time delay between the actualdata and the data shown on Analytics.Therefore you should see morevisitors on Analytics tomorrow. A change in your bids should affect your account immediately. HoweverI'm not 100% sure with this question, too. As I said, post questions like that on GOMCHA or use the GOOGLEcompetition help. Cheers, Steffen
