You are correct on all counts:
I think Unique Visitors means the UV of the page that the test is running.
That is correct.
If my test component is at the bottom of the page, users will still be counted in report even if they didn’t scroll down to be able to see my change?
That is exactly how i works because the mbox would have fired.
Is it to create a mbox that only fires when users scroll down to the test component and then set the test target audience to that mbox?
This is a very creative solution to making sure that eyes are actually on the mbox.
If this helps you don't forget to like, mark as helpful & mark as answer as that helps me Hope you have a wonderful day.
