My team is trying to decide which is best practice. We currently have a test where we have a Control that does nothing on the page (Default Content), and a Challenger where if the visitor lands on the control page, they get redirected (via Target Redirect Offer) to another page (let's call this page B). For setting up the test and for visitor count to be accurate for the test, should we also include the mbox for page B for this test (and keep the offer as Default Content)?
One argument (for if we include page B mbox in the campaign) is that if the visitor copies the redirected URL and uses another browser, they will be counted as another visitor.
Another argument (for if we do not include page B mbox in the campaign), is that if the visitor copies the redirected URL and uses another browser, they will not be counted in the campaign conversion.
Which one is correct? Also, do we need to do the same for Standard? We have an mbox that is common on all our pages, and Page B location would be added by page URL.
