I haven't made this mistake before, but I'm curious to know what would happen. Say you have two websites, A and B. Each has 100 pages. You add them to your Analytics account. When you are added the Analytics tracking code, you accidentally added the tracking code for website A onto 50 pages of website B, and you added tracking code for website B onto 50 pages of website A. So now half the pages of each website carry the other site's tracking code. Which of the following should happen: a) You will only be able to see the report for the tracking code that you add correctly. Meaning you can only view the traffic from 50 pages of site A and 50 pages of site B. b) Google Analytics will consider the 50 pages in site A to be in site B, and will show you a wrong report. c) Google Analytics will be intelligent to tell the difference in domain, and give you a correct report. If you have done a mistake similar to above, please share the outcome.
i dont know why you posted this thread, analytics treats visits to separate Url's as unique and unrelated, this is how you would expect analytics to work
GA will only count the visits to the site A within the site A profile. it will not count traffic to other domains with the same analytics code.
