Amazon affiliates site that bring orders

Hi Guys,

I'm recently started an amazon affiliates site, and just signed up to amazon associates program.
In the form that i completed i had to add the website that i'll be using for this program. So now i'm wondering:
If i'll build more sites for amazon affiliates, should i always update this list with my website?
Or, after my approval, it wont matter that much, where orders came from?

Can someone please advice me on this question.
Thanks to all in advance!
