  35. 35. #EXTRA
  36. 36. Bounce Rate My new site’s bounce rate is so good, it’s less than 10% You may have added a new set of tracking code without removing old code Two codes = two pageviews = no bounces!
  37. 37. Other pages I can see (other) in my Pages report, that’s not one of my pages! You probably have too many unique page URLs and have run out of rows Exclude parameters in the admin settings to remove unique strings and group URLs together
  38. 38. Differences Why am I getting different results for the same thing? Check the sampling level, is it different on the two reports? When adding segments or date comparisons, GA doesn’t always have the accurate processed data to hand.
