Question about Amazon Affiliate

Hello all

I have a question about Amazon Affiliate. I have a Authority Niche Site and I have many top ranking keywords for some niche.

1. Will I create many tracking id under 1 Affiliate Account ( each tracking id will use for each niche) and I can see report income for each tracking id only?

2. If buyer buy by using Gift Card. Will I get commesion from Amazon or only buyer use Credit card?

Thanks

You see people from Amazon buy many products out there along with yours, why do you even need this ID's, you created good site and it should be enough to make any profit out there. As for second question - I think that yes you will get credit.
